The little metal spheres inside add a sensation I didn't expect, way more intense than a plain sleeve. It stretches enough to fit comfortably without feeling like it'll tear, and the 13.5 cm length works well for us.

Wasn't sure about the bumps at first but the stretch makes it fit way better than I expected, and the extra length really shows. Feels intense in a good way.

The little metal spheres along the surface add way more sensation than I expected, and my partner noticed the difference right away. The stretchy fit makes it easy to put on and it stays put. Honestly better than the plain sleeve I had before.
