NUTTER is a veiny, fleshy sack thats made to encase your balls and plump up your package.Think SACKSLING but with blubberier material and a tighter, more realistic nutsack design.NUTTER is made from FLEX-TPR so its thick and blubbery but squishy enough to mold n` stretch to the shape of your sack.A built-in version of our best-selling UNIT-X cock-sling holds NUTTER tightly to your junk like a second skineven when youre pounding a beefy bubble butt or jerkin` your greased up meat.The bottom of each nut has a drain hole for your sack sweat which also doubles as an opening for electrodes.
