One of the most popular sleeves available for The Fleshlight its textured waves along the length of the canal provide a unique masturbation experience. The sleeve is soft and pliable and is designed to be used with The Fleshlight case which firmly supports the sleeve and allows for a realistic penetrative experience. The opening is shaped like a woman's vagina but there are other opening designs available that resemble a mouth, ass, or a slot. At ten inches in length it can handle most things placed into it. According to the manufactures web site The Wonder Wave on a scale of 1 to 5 provides a stimulation level of 3. With an inner canal diameter of half an inch the textured wave canal wraps the user with 360 degrees of stimulation that can be felt from tip to base especially during slow and steady stroking. The sleeve is too floppy to use without the case so if you do not own a Fleshlight case you should get one to get the maximum benefit from the sleeve. Although simply placing an erection into a Fleshight and stoking at whatever pace one desires works, hands-free use truly maximizes the Fleshlight characteristics and makes for an incredible penetrative masturbation experience. This can done by placing the case between a mattress and box-spring or any similar item and kneeling in front of it to simulate a doggy style position. The case is sturdy enough to handle the weight of the mattress and the sleeve can handle the hardest thrust you can throw at it.

The Fleshlights are made from a patented formula that is called Real Feel Superskin that is soft, smooth, and very realistic both in appearance and in the way it simulates penetrative sex. It is non-allergenic and latex free and retains heat just like real skin. The thickness at the opening of the sleeve allows the material to respond like actual skin during hard thrusting and the textured canal is suitable for any user. There are no unpleasant odors that were noticed upon removing from the package.

The Wonder Wave Lady replicates the vagina orifice and is realistic in its appearance. Both the inner and outer lips are visible as well as the clitoral hood with the clitoris peeking out from underneath the hood. The lips move like real lips when spread apart and during thrusting which adds to the visual stimulation when using the sleeve. The sleeve functions extremely well both visually and physically and provided a very realistic experience, placing the sleeve in warm water before use adds to the experience as well. The size of the sleeve and case will accommodate most men comfortably and only the very well endowed men may be able to bottom out in one of these. The case does make the Fleshlight a little on the bulky side so make sure you have some place to stash it if you do not want to have to explain to someone what it is. The Fleshlight can be packed in checked luggage for those of you who wish to travel with one. There is no metal on the case so you do not have to worry about airport security finding it.

The Wonder Wave is safe to use with any water based lubricant and cleaning is relatively simple. The easiest way to clean is by running warm water through one end and letting it run out the other. It is easier to keep the sleeve clean if you pull out before ejaculation, you can ejaculate in the sleeve it just takes longer to flush everything out. It is important to let the sleeve dry completely inside and out before storing. Storing the sleeve wet can allow mold to grow although the manufacture says that wiping with Isopropyl Alcohol will resolve any mold issues should they arise. If the sleeve starts to get sticky over time corn starch rubbed over the sticky areas will remove the sticky feeling. When the sleeve is completely dry, we always sprinkle some cornstarch on it just to keep it ready for the next use. Baby powder or anything containing talc should NOT be used on the sleeve.

The sleeve come packaged in a plastic sleeve placed inside a metal tin. Also included is a single use water-based lubricant that has the chance of falling inside the sleeve during shipping. The manufacturer includes an sheet of paper informing the user of this and to check the sleeve clear before using for the first time to prevent personal injury.
