This veiny fleshy sack is made to encase your balls and plump up your package. Made from Flex-TPR so it’s thick but squishy enough to stretch to your shape. The bottom of each nut has a drain hole for sweat which also doubles as an opening for electrodes. Also works as a packer for filling out a jockstrap or some tight gear. Penis hole diameter: 1 in. (2.54cm). Ball hole diameter: 3.25 in. (8.23cm). Total length is 5 in. (12.7cm).
