Based on the best selling UNIT-X, this STRETCH version adds more squeeze to your sack...it grips the base of your dick and balls while pushing your nuts down low in their ball-bag. It`s sleek and super stretchy just like the UNIT-X, but with an extra inch of rubbery ballstretching.Ox Balls invented the original Cock Sling and NUTTSLING...this fucker works the same way but its slimmer and fits better with no extra bulk...nothing feels like a sling on your dickit feels just like when you grip the base of your meat and balls with your hand and squeeze, not tight like a Cock Ring, it grips all of your junk...and this version stretches your nuttsack too!There`s an inner ring near the bottom that keeps your balls, (even high and tight ones), pushed down...and its squishy enough it`ll fit even huge ball-sacks...Made from out exclusive TPR blend, its non-toxic, phthalate free, and no scent...our blend feels like the best silicone but stretches further.Safe with any lube, but always wash your toys in warm soapy water after use and store separate from your other toys--they will last longer, (and wash your junk as well)we recommend wrapping smaller toys in a bandanna or storing dildos in a clean cotton gym sock.
