We've taken our best-selling sackling design and turned it into a super meaty masturbation sleeve - the SackJack. The SackJack is a dual-purpose ball sling and masturbation toy made from our signature Flex-TPR, making it super soft and supple. It moulds perfectly to your genitals and feels like you're pleasuring your second skin. The shaft of the SackJack features nubs and ridges that provide an incredible sensation as they glide over your slippery flesh. The opening at the end even allows you to use it while urinating. Best of all, the SackJack looks tantalising as it wraps around your parts and works your flesh. The clear, frosty colour lets you see your swollen member as you work out the thick, creamy load. Inside the Ballsling is a ribbed ring that ensures your testicles stay firmly in place and in their new sweaty sack. There are two openings on each side for drainage during a hot and intense watersports scene or the perfect size for contact points for shocking electro play.
