The Ultracore system by Oxballs is for the big ballers that love the most bag-gripping stretch! You get the amazing CORE ball stretcher with its outer ribs that provide a super long stretch. It stays taller on your ball sack with a more padded grip in the middle for the tightest bag-squeeze. You also get the rib-gripping rubbery Axis power-ring. This power ring has a channel of ribs that morph with the outer ribs on the core stretcher. The Core ball stretcher is an amazing ball stretcher on its own but add the Axis power ring on top of the Core and you’ll get a full force bag squeeze. Using a little lube, stretch the Core ball stretcher and drop your bag through, this is easiest just out of the shower as your bag hangs lower. The inner hourglass shape will hold you where you put it and if you're after the max squeeze slide the stretchy Axis ring on the Core's middle rib for grip. Made from an extra soft Plus+SILICONE blend, it feels firm but smooth and velvety to touch.
