Jack-It Frost 伸縮器曲線

The textured curves inside create a very distinct, pleasurable sensation that I haven't felt in other sleeves. It's easy to clean, and the transparent material holds lube well without getting sticky.

The clear material feels surprisingly silky, not sticky at all, and the internal texture adds just enough sensation. I used it with a bit of lube and honestly didn't expect it to feel this smooth against the skin.

The clear exterior is surprisingly soft to the touch, and the curves make it easy to grip during use. I only wish the texture inside was a bit more pronounced for the price.
