Tenga 3D Sleeve Holes are the only male masturbatory sleeves that you don’t have to hide in a drawer.
Because the Internal Details of the sleeve are also the External Design.
When you’re ready to use the 3D Sleeve, simple turn it inside out so that the design is on the inside. Let the bumps, ridges and other textural protrusions provide the ultimate sensual masturbatory experience.
The sleeve's protruding blocks rub along you for a firm sensation, while the receded blocks cling onto you accentuating the tone. This sleeve provides a strong and firm sensation.
