The Unit-X from the brand Oxballs is made for comfort so it is soft and stretchy. It has enough stretch to go around the penis and testicles. The Unit-X is wonderful for firmer, lasting erections and helps delay ejaculation. The toy rests against the pubic mound with the penis coming out of one hole and the testicles through the other. Made of 100% TPR which is non-toxic and pthalate free. Safe with water and silicone based lubes.
