The CORE ballstretcher with power-grip AXIS ring for the most stretch by OXBALLS

ULTRACORE system is for the really big ballers that dig the most bag gripping stretch! You get the amazing CORE ballstretcher—it’s got 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–its got channel ribs inside that morph with the outside ribs on the CORE stretcher. 

CORE ballstretcher is a amazing ballstretcher on its own—on your nuts the inner smooth tunnel wraps your sack with a medium firm squeeze, but add AXIS power ring on top of the cogged CORE and get the most MAX BAG SQUEEZING.

We sweat the BIG stuff when we design for your ball needs, we put extra thought into new ways to stretch you harder—we do so much ballsack research, seriously we look at your balls a lot), we see you stretchers stacking our rings for insane sack squeezing—ULTRACORE has the features to max out your stretch right.

HOW TO WEAR: a little lube or spit, gym sweaty showering is good, 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 grips

Made of our extra-soft Plus+SILICONE blend, it’ll keep the grip firm enough with a smooth velvety rubbery comfortable stretch, and the right grip for more play.
