Oxballs Knotter Cocksheath Night Edition is a lush rubbery silsoft silicone blend with a smooth velvet black colour. This is a softer squishier formula for the hardest and darkest of play.The Knotter is so fluid smooth it stretches and glides in but the base gets seriously fat with wide thick humps surrounding the base of your shaft ready for that big shove. It’s covered in slick nubs for an even more feel (if you can take it all in).This sheath strokes you while you pump the inner shaft tube is loaded with nubs and a larger inner shroom head space more than any other sheath!
