With TRI-POWER from Boxer, you get a ball stretcher and cock ring in one. The black ring is securely placed at the base of the penis, after which you can feel the pleasant pull it gives in the testicles.

Depending on how you position it, it can be used as a cock ring that holds extra far down on your shaft, as a ball stretcher and cock ring at the same time, or as a ball stretcher that separates the testicles.

It is ideal for CBT, but also for those who want to feel a pull in the testicles during all types of sex. 

The different sizes mean that you can use them, whether you are experienced in ball-stretching or completely new to it.

Length of ball stretcher:

Small: 3 cm

Medium: 4 cm

Large: 5 cm
