OxBalls Ultracore Core Ballstretcher w/ Axis Ring Blue Ice

For those who want serious sack stretch, the OxBalls ULTRACORE system is built to deliver. This two-piece set pairs the CORE ballstretcher with the AXIS power-ring, and together they take bag squeezing to a whole new level of intensity.

The CORE ballstretcher does plenty on its own – the inner smooth tunnel wraps your sack with a medium firm squeeze, while the inner hourglass shape holds it exactly where you position it. Outer ribs run along the CORE for extended stretch, keeping it taller on your sack with padded grip in the middle for a satisfying bag-squeeze. When you’re ready to go further, slide the stretchy AXIS power-ring onto CORE’s middle rib grips. The channel ribs inside the AXIS lock into the outer ribs on the CORE, doubling the squeeze and maxing out the stretch.

How the CORE and AXIS work together

The AXIS power-ring is designed specifically to grip the CORE’s ridged exterior – those channel ribs inside the ring morph with the outside ribs on the CORE stretcher for a locked-in, intensified squeeze. To put it on, use a little lube or spit, stretch the CORE and drop your bag through, then adjust to where you want it. The hourglass shape keeps everything in place. Slide the AXIS ring over the top when you want maximum effect. Both pieces are made from OxBalls’ extra-soft Plus SILICONE blend – smooth and velvety against the skin, with just the right amount of firm grip for extended wear and play.
