Introducing CORE, our newest ballstretcher inspired by our popular SQUEEZE model. Designed to fit your nuts snugly, CORE features a smooth hourglass inner sleeve that wraps your sack with a medium firm squeeze, while outer ribs keep you stretched down for real low-hangers. To wear, simply apply a little lube or spit, then stretch CORE and drop your bag through. Adjust to your desired position—the inner hourglass shape will hold it in place. Made of our extra-soft Plus+SILICONE blend, CORE offers a velvety rubbery stretch and the perfect slippery grip for more play. Use with any OxLUBE lubes for longer comfort. At Oxballs, we're dedicated to crafting the best ballstretchers for all types of nutbags and all sizes. We use, play, and test our gear to ensure you get the coolest features and new ways to play hard.
