CORE ballstretcher best feature is the outer ribs for superlongspringy-stretch: it stays taller on your sack with more padded grip in the middle for a fatty bag-squeeze.

Based on our most popular SQUEEZE ballstretcher, CORE fits your nuts with a smooth hourglass inner sleeve on your nutbag… this slick tunnel wraps your sack with a medium firm squeeze while the outer ribs keep you stretched down for real low-hangers.
