พาวเวอร์ พลัส แหวนซิลิโคนนุ่มกระชับ - แหวนองคชาตสีดำ - ชุด 3 ขนาด - LV443001B

The silicone on these is thicker than I expected, and the stretch is no joke—the small one opens right up to about 7.5 cm without feeling like it's going to tear. Started with the medium and it held comfortably the whole time, plenty firm but zero pinching.

The three sizes mean you can actually find the right fit instead of guessing, and the medium one's been perfect for me. Silicone has just enough stretch to stay comfortable but still does what it's supposed to.

Wasn't sure about the thick silicone at first but it's got plenty of stretch and never pinched. The three sizes are handy since the small one fits snug while the bigger one's better for longer wear.
