The Truckt set 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 but still has a good hold. Since there are two rings, you can wear them in a few different ways including using one as a small ball-stretcher. This set is great for beginners because one ring is sized for just the shaft and one ring to go at the base and behind the testicles. A great way to try different styles of rings without having to buy multiple packs. Truckt is wonderful for firmer, lasting erections and helps delay ejaculation. Made of 100% TPR which is non-toxic and phthalate-free. Safe with water and silicone-based lubes.
