Biird | Riin | cockring set

A very nice set of silicone cock rings for more intensity and long-lasting pleasure.
Riin is made of ultra-soft, flexible silicone that's comfortable to use and move with. The rings are designed for a secure fit that subtly slows blood flow. The encased feeling is pleasant, and the effect is a firmer erection and can prevent premature ejaculation.
The set includes three different sizes, so you'll always find the perfect ring to suit your preference and mood. Mix and match, and discover what feels best.
TIP : Use a water-based lubricant.
