Review · Masturbator · Full-size cast sleeve
Fleshlights’ cast of Sky Bri with the Celestial texture reviewed against the manufacturer’s own specifications and packaging print. Housing 247,65 × 98,43 millimeters, removable sleeve in Real Feel Super Skin, stepless suction control, and a nine-step care routine.
A mechanical product with unusually well-documented dimensions: the housing is 247.65 × 98.43 millimeters according to the manufacturer’s own print on the packaging, the sleeve is removable and replaceable, and the suction power is adjusted steplessly. What you pay for is maintenance—nine steps after each use, no soap on the sleeve, and one hour of drying time—and a specification where neither the channel’s dimensions nor the product’s net weight is published.
Fleshlight Girls Sky Bri Celestial is a masturbator in the manufacturer’s largest and oldest product family: a removable sleeve made of the material Real Feel Super Skin, mounted in a hard casing shaped like a flashlight. What makes this particular item a Fleshlight Girls product is that the opening is cast directly from a named person — in this case Sky Bri — and that the inner channel has its own texture with its own name. The texture is called Celestial.
The specification looks like this. The casing measures 9.75 inches in length and 3.88 inches in width, which the manufacturer itself converts to 247.65 and 98.43 millimeters, respectively, on the front of the package. The size class is full size, which, according to the manufacturer, accommodates 9 to 10 inches in length and up to 7½ inches in circumference. The casing is pearly white, the gel has the color designation Light Flesh, the fit is classified as Tight, and the texture class as Intense. Suction is adjusted steplessly with an adjustable cap at the bottom. There is no motor, no battery, and no electronics at all in the product. In this market, it is sold by Fleshlight.
This review is exclusively about the vaginal variant with EAN 810476012052. The number can be confirmed in two independent places with the manufacturer: partly in the variant table in Fleshlight’s own store data, where the row Celestial (Lady) / With Case carries that exact barcode, and partly on the manufacturer’s photo of the back of the package, where the same digits are printed under the barcode symbol. The anal sister product, texture Asstral, carries 810476012069 and is a different item even though both are listed on the same product page.
The manufacturer describes Celestial as a texture with intricate twists and spirals that wrap around and create a swirling sensation, and that farther in transitions into two narrower grips that pull together the channel. These are two separate principles in the same sleeve: the first half varies the direction of contact, and the second half varies the diameter. The cross-section image on the back of the package shows the same thing graphically — a long, spiral-twisted passage interrupted by transverse constrictions.
Asstral, the anal texture on the same product page, is instead described as several dense grip zones and different shapes that create varying pressure throughout the channel. So the difference between the two is not only which opening sits outermost, but also how the channel inside is constructed. What can be established is that the person who buys based on the appearance of the opening and the person who buys based on the texture’s construction may end up with different items, and that the two have different EAN.
Retailers describe the interior as three chambers with ridges, bumps, and pressure points. This is a shop claim and not the manufacturer’s own wording—Fleshlight talks about spirals followed by two narrower grips, not about a certain number of chambers. The information doesn’t contradict each other in substance, but the number three comes from the retailers.
Fleshlight sells Sky Bri in four variants from the same page, and that’s the most common source of mix-ups within this product family.
The price difference between with and without case is 20 dollars from the manufacturer. That says something about how much of the product’s value lies in the plastic case, and that’s also the reason someone who already has a Fleshlight should check which variant a store in this market actually lists. In this market, Fleshlight sells the product.
The material issue is the only feature of an intimate product that can’t be compensated for with experience or care, and with a masturbator without electronics it’s also practically the entire product. There’s no motor to assess, no app, and no battery. That leaves two parts: the sleeve and the case.
The manufacturer calls the sleeve material Real Feel Super Skin and describes it in its FAQ as a mineral-based patented polymer made with white, food-grade mineral oil. It is unusually specific for this category. Most manufacturers are content with the label TPE, which says nothing at all about which plasticizers are included, and the information about which oil is used is the decisive difference—the softness in an elastomer comes from the oil phase, and it is that which determines whether the material is stable over time.
Two stores instead list the material as TPE + ABS. It is one store’s claim, and it should be read as a simplification: TPE then stands for the sleeve and ABS for the hard housing. The manufacturer does not write TPE or ABS anywhere, and when the store and manufacturer differ, the manufacturer’s wording applies. The practical takeaway is still the same, though—the sleeve is a soft elastomer, and the housing is hard plastic.
One characteristic that follows from the material selection is that the sleeve is not pore-free in the same way as silicone. That is why the manufacturer recommends renewing powder, a powdering agent that is supposed to keep the surface silky and prevent it from feeling sticky, and that is also why the care routine is so much more involved than with a silicone product. That is the single most important difference from a silicone vibrator, and it should be considered before buying rather than discovered afterwards.
The manufacturer describes the housing as a robust container that resembles a regular flashlight. In this particular model, it is pearly white—the manufacturer’s own color designation is Pearl—and on the side of the housing, the text Fleshlight Girls is embossed directly into the plastic. The sleeve is removable, which is the prerequisite for being able to clean it properly, and it is also what makes it possible to replace the sleeve while keeping the housing.
Phthalates are a group of plasticizers used to make plastic—especially soft PVC—flexible. The Swedish Chemicals Agency (Kemikalieinspektionen) describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This product category is repeatedly subject to supervision precisely because it contains soft plastic against skin and mucous membranes.
On the back of the package, it is printed that the product is safe, non-toxic and phthalate-free. This is a commitment the manufacturer makes in print on the product itself, not just in marketing text on a website, and it makes it more worthwhile than a loose phrasing in a product description. The same page also bears the origin marking Made in the USA.
What is, however, missing is a complete material declaration. The manufacturer does not publish either the polymer’s chemical designation, its hardness in Shore A, or any information about which additives are included beyond the mineral oil. It’s a real gap in the specification, and anyone who wants to be able to compare the material against a silicone product on technical grounds has nothing to compare it with. The casting method, however, is patented: the manufacturer’s patent page lists US 11 234 893, titled Method And System Of Creating A Replica Of An Anatomical Structure.
The dimensions of the housing are printed directly on the front of the packaging: length 9.75 inches, i.e. 247.65 millimeters, and width 3.88 inches, i.e. 98.43 millimeters. This is the manufacturer’s own information and the most reliable dimension specification available for the product. One listing gives the total length as 24.76 centimeters, which is the same number, while two other retailers both round it to 25 centimeters. So the difference is rounding, not disagreement.
The insertable length, however, is a store listing. One listing states 21.6 centimeters, another gives 21.60 centimeters, and a third uses the same figure under the heading penetrated length. Fleshlight publishes no channel length and no channel diameter — the closest the manufacturer comes is the size class full size, described as suitable for 9 to 10 inches in length and up to 7½ inches in circumference. That three independent resellers state exactly the same 21.6 centimeters figure suggests the number comes from the same wholesale source material, not from three separate measurements.
The weight information deserves a clear note. In the manufacturer’s own store data, it’s 907 grams—but the same 907 grams appears on all four variants, including the two sold entirely without a housing. It’s therefore a flat-rate shipping weight and not the product’s weight. One store listing instead lists 0.73 kilograms for the packaged item, which is a store listing and a more reasonable order of magnitude for housing, sleeve, and cardboard together. The manufacturer publishes no net weight for either the sleeve or the complete product, and anyone who needs to know exactly how heavy the object is in hand gets no answer from the specification.
The packaging’s outer dimensions also come from the store side: One store listing gives 25.50 × 10.00 × 10.00 centimeters. It’s worth knowing for a practical reason—the box is neither small nor anonymous, and it has a photograph of the model on the front. If you want to store the product in its original packaging, it takes up about as much space as a large thermos, and it’s not discreet.
The manufacturer summarizes use in three steps on the back of the packaging: open, lubricate, enjoy. It sounds simple for the simple reason that it is. The product has no buttons, no display, and no charging port. It is powered, as one store’s specification table puts it, by manual power.
A free sample lubricant from the manufacturer’s own FleshLube is included in the package according to what’s printed on the cardboard. Otherwise, the delivery consists of the housing with the embossed star design, the removable Real Feel Super Skin sleeve, and the packaging — the store’s description of the contents, which matches the manufacturer’s own pictures.
The suction is controlled by an adjustable cap at the bottom of the housing. The manufacturer puts it as follows: the rear cap regulates how much suction builds up, and the same promise is printed on the front of the packaging under the heading “adjustable suction.” The principle is mechanical and simple: when you screw the cap on to seal the channel, the vacuum increases; when you unscrew it and let air in, resistance decreases.
What can be said is that the adjustment is stepless. The manufacturer does not publish a scale, fixed positions, or a measurement of how much vacuum builds up. Compared with an electronic product, where the number of settings is a number in the specifications, it’s both an advantage and a disadvantage. The advantage is that there’s no step between two settings that fit you. The disadvantage is that the setting can’t be reproduced exactly and can’t be compared between products.
A practical consequence of the design is that the cap also has to be open when cleaning, since the water needs to be able to run through the channel. So, having the cap sit loose is not only a control feature but also a prerequisite for maintenance.
The manufacturer is unambiguous in its FAQ: the products may only be used with water-based lubricant, and any other type can damage the sleeve over time. It’s guidance that applies to the entire range, not just this model, and it matters more with an elastomer than with silicone, because a damaged Super Skin surface can’t be restored.
Silicone-based lubricant, then, should not be used. Nor should you use oil-based products such as coconut oil, which leaves a film that’s difficult to remove and also changes the material’s surface properties. The manufacturer sells a water-based lubricant itself under the name FleshLube and, as mentioned, includes a sample package in the box, which in practice means that you can use the product right away without first having to buy it.
A tip that follows from the choice of material rather than the manual: water-based lube dries faster than silicone-based, and with a long channel of this kind it often needs to be topped up. It’s one of the few practical downsides of the fact that the material requires water-based lubrication.
The care routine is the part of this product that differs the most from a typical vibrator, and it’s also the part that’s most often underestimated before purchase. The manufacturer’s own care guide describes a routine in nine steps that should be followed after each use.
According to the manufacturer’s guide, the following order applies. Remove the sleeve from the housing. Rinse the sleeve in lukewarm water for about thirty seconds. Fill it with water, hold it over the outlet hole, and shake for five to ten seconds. Rinse once more. Wash the hard housing with soap and water. Spray the sleeve in and out with the manufacturer’s antibacterial FleshWash. Let it dry completely. Dust with renewing powder. Reassemble and put away.
One detail in that guide deserves to be highlighted in particular, because it’s easy to miss and easy to get wrong: soap may only be used on the housing, never on the sleeve. The manufacturer states it explicitly. Soap breaks down the elastomer over time, and that’s exactly the shortcut a typical user of a “regular vibrator” would otherwise take. The guide also warns that mold can form both inside and outside the sleeve if the product isn’t cared for properly.
The manufacturer lists drying times for its own drying device: 20 minutes for Quickshot models, 40 minutes for Flight and GO models, and 60 minutes for full size. Sky Bri Celestial is a full-size product, so an hour is the figure that applies—and it assumes you’ve bought the drying device separately.
The manufacturer does not publish how long air-drying takes without the drying device. What can be said is that it takes longer; it should be done in a cool, dry, and ventilated place according to the manufacturer’s FAQ, and the product shouldn’t be assembled until the sleeve is completely dry. In practice, that means the product is occupied for quite a while after each use, and it’s a real difference compared with a silicone product that’s dried off with a towel and put away right away.
Because there’s no battery, there’s also no cell that degrades and sets an end limit for the product’s lifespan. What wears out is the sleeve. The manufacturer doesn’t publish an expected lifespan or a number of uses, but the factors that determine it can be read from the care instructions: which lube is used, whether soap has gotten onto the sleeve, whether it was dried completely before storage, and whether renewing powder is used.
Since the sleeve is removable, there’s one consequence that rarely shows up in store text: the housing outlasts the sleeve. When a sleeve has been used up, it can be replaced with a new one — Fleshlight sells the same texture in the variant without a housing for $59.95, versus $79.95 for the complete product. That makes the product more repairable than virtually everything else in this category, and it’s an argument that carries more weight the longer you plan to own it.
One store lists the product as 100 percent waterproof, and another indicates waterproof: yes. Both are store claims. Fleshlight does not publish any IP rating for this product, neither IPX7 nor any other, and in this context that’s completely logical: IEC 60529 classifies enclosures for electrical equipment, and this product contains not a single electrical component.
Instead, the practical guidance should be read from the manufacturer’s care guide, which builds the entire cleaning routine on running water through the sleeve and soap and water on the housing. So being able to tolerate water is a prerequisite for it to be possible to care for, and the manufacturer treats that as a given rather than as a rated feature. The difference versus a battery-powered product is that the absence of an IP rating here is not a warning — there’s simply nothing to enclose.
What, on the other hand, is not shown anywhere is temperature limits. The manufacturer does not state a maximum temperature for the sleeve, but recommends its own Sleeve Warmer, which, according to the printed information on the packaging, heats the sleeve in under five minutes. The fact that this product exists at all and is marketed is, in itself, a message that heating should be done in a controlled way and not by putting the sleeve in boiling water.
One shop sells this product, for £62. The price was checked on 26 September 2026 and may have changed since.
The weight information, 907 grams, is listed for all four variants, including the two that are sold without a housing. It is the shipping weight, not the product’s weight.
Four comparisons are relevant, and they all fall within the same brand. It’s not a coincidence: Fleshlight states on its own that more than 20 million units have been sold, and in practice the sharpest competition for a Fleshlight Girls product is other Fleshlights that use exactly the same housing and the same materials. The information below comes from the manufacturer’s own product data.
Fleshlight Classics is sold under the name Pink Lady. The Lady / Original variant has EAN 810476017002.
The specifications are close to each other. Both are full size with the same size class, up to 9 inches in length and 7½ inches in circumference. Both have a removable Real Feel Super Skin cover, an adjustable back cap, and the same care routine. What the Pink Lady lacks is the casting: its opening is a generic shape, not a replica of a named person, and the housing is black instead of pearl white.
The conclusion is simple. If the casting and the named texture are what you’re paying for, then that’s what you get. If you’re only after the feel, you get the same material, the same housing, and the same care requirements—and Pink Lady Original is also available in six different textures within the same product family from the manufacturer.
It’s sold as the Pink Lady Stamina Training Unit with EAN 810476017729. It’s full size, classified with the fit Tight, and has a gold-colored housing.
The Tight fit classification is the only technical purpose that distinguishes it from Classics—and it’s the same classification that Sky Bri Celestial has. The difference lies in the purpose: the manufacturer markets STU explicitly as a tool for building endurance, with a texture engineered to be more intense than average. Sky Bri Celestial, in turn, is classified as Intense in the manufacturer’s own texture classification.
What can be established is that the two are at the same level in the manufacturer’s classification system but have different texture construction. If you want the spirals and the two narrower grips in Celestial, you should buy Sky Bri. If you want a texture designed around a training purpose rather than around a person, STU is the way to go. In this market, Fleshlight Girls Sky Bri Celestial is sold by Fleshlight.
The GO series is the manufacturer’s compact format. GO Stamina Training Unit Lady carries EAN 810476019785 and has a list price of 59.95 dollars from the manufacturer. The size class is GO Series, which according to the manufacturer’s own classification fits up to 8 inches in length and 6½ inches in circumference—so it’s smaller both in length and in circumference than full size.
The difference is purely practical. A full-size housing at 247.65 millimeters is hard to store discreetly and hard to take with you. The GO housing is shorter and narrower and significantly easier to put away.
The person who chooses GO sacrifices two things: the mold from a named person, which isn’t available in that series, and the longer channel. The person who chooses full size sacrifices storage space and portability. There’s no right answer — but it’s worth measuring out 25 centimeters in the box where the product will actually be placed before ordering.
The Quickshot format is the route into the same material. Stamina Training Unit Quickshot Lady & Butt carries EAN 810476010973. It’s a significantly smaller product with an all-through channel — open at both ends instead of closed.
This construction creates three differences that matter. The channel is short, which means it doesn’t enclose the entire length. The suction regulation doesn’t work the same way, because there isn’t any closed space to build up a vacuum in. And the drying time is 20 minutes in the manufacturer’s drying unit versus 60 for full size, which is the most concrete practical advantage in the entire comparison.
If you’re unsure whether Fleshlights material and care requirements will suit you, Quickshot is a cheap way to find out. If you already know that the format works, and you want a mold, full length, and suction regulation, the price difference is justified — but it should be a conscious choice, not an assumption that more expensive is always better.
In this market, it’s sold by Fleshlight (EAN 810476012052).
For this category, the pricing check was unusually clear. The pricing check covered offers from all shops.
Shipping costs can even out some of the difference. In this market, the product is sold by Fleshlight, but shipping fees can vary—so always check the final price at checkout. Several stores also offer free shipping over a certain order value.
A note about data quality belongs here, because it affects price comparisons across the entire industry. In Lekosmeks product flow, there are two entries that carry EAN 810476012052. One of them is the correct one, item number 117473083, Fleshlight Girls Sky Bri Celestial. The other is item number 117473040, a garment — a bodysuit from the brand Daring Intimates, which has incorrectly been given the same barcode in the flow.
That entry is excluded from the table above, because it does not refer to this product. But it explains something that is worth knowing as a buyer: price-comparison services that blindly rely on the barcode in a store flow can show a ghostlike low price that you can’t actually buy. If you see a Fleshlight Girls listed at a surprisingly low price somewhere, it is almost always a data error and not a bargain.
It’s for you if you want a full-size product with a long channel and you see the impression from a named person as part of the value. It’s for you if you want to be able to regulate the craving without steps instead of choosing between fixed positions. It’s for you if you appreciate that the sleeve is removable and replaceable, and therefore you can keep the housing when the sleeve is used up. And it’s for you if you prefer a product without a battery, because that removes the most common reason an intimate product becomes unusable after a few years.
It’s not for you if you want something small and easy to store — 247.65 millimeters is hard to hide, and the packaging is neither discreet nor small. It’s not for you if you want to be able to rinse off a product in ten seconds and put it away; the care routine is nine steps long, and the drying time is one hour with the manufacturer’s drying unit. It’s not for you if you require a complete material declaration, because the manufacturer does not publish the polymer’s designation, the hardness, or the channel’s dimensions. And it’s not for you if you want vibration — there is no motor in this product.
One more thing belongs in the decision. The price difference between this item and the manufacturer’s cheaper full-size models is small. If you pay those prices, you get the impression and the named texture. However, you don’t get a better material, a better housing, or easier care — those parts are identical throughout the range.
Fleshlight does not offer a time-limited manufacturer warranty in the usual sense. In the EU and EEA, consumers buying online generally have a 14-day right of withdrawal, starting when the goods are received. Under EU rules, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. In the EU, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee).
The terms apply to purchases in Fleshlight’s own store. If you buy from any of the sellers listed above, it’s the shop’s own terms that govern returns and complaints in the first instance.
What always applies, however, when you buy online in the EU and EEA is your statutory consumer rights. In general, you have a 14-day right of withdrawal starting when the goods are received. Under EU rules, sealed goods that are not suitable for return for health or hygiene reasons are exempt from the right of withdrawal once unsealed. In the EU, the seller is liable for defects that exist at delivery and appear within at least 2 years (the legal guarantee).
