ULTRACORE system is for the serious enthusiasts who appreciate maximum bag-gripping stretch! You receive the incredible CORE ballstretcher, featuring outer ribs for an extended stretch: it maintains height on your sack with added padded grip in the center for a satisfying squeeze.
Additionally, you get the rib-gripping rubbery AXIS power-ring, which has channel ribs inside that adapt to the outer ribs of the CORE stretcher. The CORE ballstretcher is fantastic on its own, wrapping your sack with a medium firm squeeze, but when you add the AXIS power ring on top of the cogged CORE, you achieve the ultimate MAX BAG SQUEEZING.
We focus on the important aspects when designing for your ball needs, putting extra thought into innovative ways to stretch you harder. We conduct extensive research, observing how stretchers stack our rings for incredible sack squeezing. ULTRACORE is designed to maximize your stretch effectively.
To wear, use a bit of lube or spit; gym sweat or showering works well. Stretch the CORE and drop your bag through, adjusting as needed. The inner hourglass shape will hold it in place. For maximum squeeze, slide the stretchy AXIS ring onto CORE's middle rib grips.
Made from our extra-soft Plus SILICONE blend, it provides a firm grip with a smooth, velvety, comfortable stretch, ensuring the right grip for more play. Oxballs creates the best ballstretchers for all types of nutbags, sizes, and desires. We use, play with, and test our gear to ensure you receive the best designs with the coolest features and new ways to enjoy.
