OptiMALE シリコンコックリング太め3個セット（3ピースキット）- ブラック

Was a little worried the 50mm would be too loose, but the silicone grips well and stays put without pinching. The different sizes let me find what works for that specific moment.

The 45mm ring is the sweet spot for me—gives a solid boost in girth without feeling like it’s cutting off circulation. The silicone is softer than I expected, so it’s comfortable to slip on and wear for a while.

The 45mm is the sweet spot for me—it’s snug but the silicone gives just enough give to slip on without a struggle. I’ve worn it for about 20 minutes and it held its shape the whole time, no pinching or rolling.
