BULLBALLS-1 is one most popular silicone ballstretchers from OxBalls.
This thing just fits and feels right as it is made of pure platinum cure medical grade silicone, (only the best from us pigs at OxBalls), the stuff feels like skin - warms up to body temp fast, keeps your balls sweaty and warm.
It stretches your sack gently yet firmly, but without pinching, no blue balls.
High quality silicone doesn't irritate skin, (it is the safest, purest, highest quality material available).
BULLBALLS-1 changed ballstretching - OxBalls had so many fan letters from low hanging ball-boys raving about this one.
This design still is the perfect balance of stretch, weight, material, size, and it looks hot, industrial and if you have huge nuts, we envy you and hate you, but we make a larger size called BULLBALLS-2 just for you lucky fuckers.
