Ultracore Core Ballstretcher with Axis Ring

The Ultracore is Oxballs' ballstretching system for guys who want the most sack-gripping squeeze. You get the Core ballstretcher, with outer ribs for long stretch and a padded middle for a fatty bag-squeeze, plus the rubbery Axis power-ring, whose inner channel ribs lock onto the Core's outer ribs to double down the squeeze.

• Two-piece system: Core ballstretcher plus Axis power-ring
• Core wraps your sack with a medium-firm squeeze; the inner hourglass shape holds where you put it
• Add the Axis ring over the Core's ribs for maximum sack squeeze
• How to wear: a little lube, stretch the Core and drop your sack through, then slide the Axis ring onto the middle ribs
• Extra-soft Plus+SILICONE blend: smooth, velvety, and non-toxic; phthalate-free
• Lube safe: water-based or silicone
• Care: wash after use in warm soapy water, air dry, store separately
