The NEO SHORT is a short ball that is great for men who are new to using stretchers or for combining with another ball. NEO ballstretchers fit and feel great. They have the same shape and thickness as the old neoprene ballstretchers, but are made from ultra-soft, stretchy Pure Platinum Silicone. NEO keeps the eggs in place... and all three styles have a thick rim around the edge, so it doesn't dig into your sack. Unlike neoprene, NEO is stretchy and feels like it's part of your sack. The NEO SHORT is a 1.25-inch ballstretcher that will fit any sack and can be stacked as you grow. The SHORT fits any sack, even with high tight eggs.
