Oxballs Ultracore Ball Stretcher with Axis Ring.
ULTRACORE system is for the really big ballers that dig the most bag-gripping stretch.
You get the amazing CORE ball stretcher that has got its outer ribs for super long stretch. It stays taller on your sack with more padded grip in the middle for a fatty bag-squeeze. You also get the rib-gripping rubbery AXIS power-ring that has got channel ribs inside which morph with the outside ribs on the CORE stretcher.
The CORE ball stretcher provides a medium-firm squeeze to wrap snugly around your sack with its inner smooth tunnel. When you combine it with the AXIS power ring on top of the cogged CORE, you can experience the maximum bag squeezing effect.
How to put this on: Just add on a little lube, stretch CORE and drop your bag through and adjust where you want it, the inner hourglass shape will hold where you put it. If you want the max squeeze effect, slide the stretchy AXIS ring on CORE's middle rib for grip.
