The Tenga Flip Hole Black is the perfect toy for the male-bodied individual looking for the ultimate jack-off aid to take solo-time to the next level. It is a standard, hand-held masturbation sleeve with a revolutionary interior. Its intense stimulation is not for the faint of heart, so a person looking for a light ride will probably be overwhelmed. It is especially designed to stimulate the head, and massage the shaft during use. It is great for both solo masturbation or with a partner, although it tends to work best when held by its user. People with extremely thick penises may find it a snug fit because of how tight it is inside. It has a decent length, though, so the more the merrier. The end orbs are the icing on the cake, and it would definitely be disappointing for someone under about 4.5" in length, but the rest of the intricate ribbing, orbs, and ridges are still very exciting. It is a bit pricey, but if you are looking for a high quality, mind-blowing sleeve, the Tenga Flip Hole series has no competition, hands down.

The outer shell of the Tenga Flip Hole is hard plastic. The interior is made of TPR Silicone, a soft, fleshy-feeling gel-like silicone that is semi-porous. It often has a sticky texture (like decorative window clings) that attracts lint and pet hair, but makes for a realistic alternative to flesh. For the most part, this is scentless. The outer shell features two openings at the side where the silicone is exposed to allow the user to create suction and control friction.

The texture on the inside is the defining feature of the sleeve.

The Tenga Flip Hole is very elegant and futuristic. It is sleek and masculine, and still very functional. It's a bit bulky, but fits in the hand well, and allows a sturdy grip during use. The suction buttons located on the outside of the Flip Hole make excellent grips. Its size makes is a bit conspicuous, although it's not at first glance obvious that it is a masturbation sleeve. It does not have a vulgar appearance.

There is a complex arrangement of ridges, orbs, and ribbing. Coming from the exterior, the first thing you encounter are silicone "doors" that give you the sensation of entering labia. In the front of the interior, there are three orbs with squiggly ridges that grip and massage. Next there are "peaks and valleys" with ridges which create slight resistance and further stimulation, followed by two more mini-orbs, the shallow ridges, which are mostly there to fill up space before you get to the end orb. Then of course comes the magnum opus in the end orb, which contours around your head. Inside and outside the end orb, there are bumps, and inside there is another mini orb which all massage and stimulate your head to create a holistic experience. The key function of the interior is to create resistance while stimulating, gripping, and suctioning your penis. The sensation is intense, so beware. When climaxing, you might find that the sensitivity of your penis, combined with the stimulation from the Flip Hole, is overwhelming.

The Tenga Flip Hole is designed with cleaning in mind. The sleeve conveniently opens up to allow you to easily rinse out after use. It is recommended that you use soap and water to rinse the interior; anti-bacterial soap will help keep bacteria from dwelling inside. After rinsing, the brace that holds it together during use is used as a stand for it to dry. The packaging that the Tenga Flip Hole comes in is great for storage. It is a clear, hard plastic case with a molded base to hold the Flip Hole and the three free lubes. The lubes are all water-based and come in different styles: the Wild is a warming lube, the Real is a realistic lube, and the Mild is a high viscosity lube. Because it is a silicone toy, be sure to avoid silicone lubes at all costs! Water-based lubes only. Also, it should be noted that certain flavored lubes have been known to warp the silicone if not rinsed off immediately, so be careful.

The toy is only rated for about 50 uses, but will probably last longer with proper care and maintenance.
