Sono No.21 Dong Sleeve Transparent

Need a little boost without the bulk? The Sono No.21 Transparent Dong Sleeve slips on, snaps into place, and turns “pretty good” into “oh wow” in seconds. You get an extra 2 inches of length plus a satisfying pop of girth, all wrapped in skin-soft TPE that bends and flexes with you. No pinching, no awkward seams, just smooth glide from tip to base.

That built-in ball strap is the real hero. Slide it under your boys, give it a gentle stretch, and the sleeve locks on tight. You can grind, thrust, twist, or pull off your best bedroom acrobatics, it stays put. No mid-session readjustments, no mood-killing slip-offs.

Because it’s totally clear, every vein and twitch still shows through, which means nothing looks fake or covered up. Your partner gets the visual thrill, you get the performance upgrade, everyone wins. Waterproof, phthalate-free, condom-compatible, and a breeze to clean with warm water and toy-safe spray.

Specs at a glance: 205 mm total length, 139 mm of insertable sleeve, 60 mm circumference, 50 mm ball strap, and a feather-light 0.30 kg. In plain English, that’s 8.1 inches long with 5.5 inches of pure pleasure zone.

Retail price sits at £33.99, but grab it here for £22.70 while it lasts. Lube up, slide in, lock on, and level up your next session without a single compromise.
