ROCK SOLID - Ribbed Donut

The ribs along the outside add a surprising amount of sensation that I wasn't expecting, and the firm silicone still has enough give to slip on without a struggle. It definitely stays put once it's on.

The stretch is forgiving enough that I didn't have to wrestle with it, and once it's on, those ribs definitely make themselves known in the best way. Silicone feels smooth, not tacky, and it's held up fine after a few washes.

The ribbed texture adds just the right amount of extra sensation without being overwhelming, and the silicone feels softer than I expected while still holding its shape firmly. I was worried about the stretch, but it slips on easily and stays comfortable during use. Exactly what I needed.
