Neo Short is a short stretcher that is perfect for beginners in ball stretching or for stacking with another ball stretcher. Neo ball stretchers fit and feel amazing. They have the same shape and thickness as traditional neoprene ball stretchers but are made from our super-soft, stretchy Pure Platinum Silicone. Neo keeps the nuts down in the sack. All three models feature a thick edge to prevent digging into the sack. Unlike neoprene, Neo is rubbery, stretchy, and feels like a part of the sack. Neo Short is a 1.25-inch ball stretcher that fits into any sack and can be stacked as you grow. Short fits any sack, even high and tight nuts. Material: phthalate-free silicone.
