TRUCKT rings hugs your meat with 2 different fits--the large one for a good grip on your c & balls and a good hard bone, the smaller one if you want more grip for rock-hard meat…or wrap your & balls with the large ring, and use the smaller ring stretched around your ballsack for tons of grip…Made of super-strong SKINFLEX-TPR, our best material for strength and serious stretch. Stretches 5X its size and snaps back every time…and this stuff feels amazing.
