SACKJACK is a dual ballsling and masturbator made from our signature FLEX-TPR so it's super blubbery and soft to the touch. SACKJACK's shaft is lined with nubs and ridges that feel amazing .

Best of all, SACKJACK's clear frosted color lets you watch all the action.

The inside of the ballsling has a ribbed ring designed to grip your balls. FLEX-TPR safe, non-toxic...and phthalate free .
