When you’re into playing with tunnel plugs and liquids, you may find yourself in need of a stopper to keep all the kinky goodness inside, and that’s where Oxballs steps in with their silicone stopper plugs. Choose size B if you’re using a medium-sized tunnel plug with an internal diameter of approximately 3.5 cm.
The plug is made of silicone and compatible with water- and oil-based lube. Clean it with warm water and mild soap or sex toy cleaner for excellent hygiene.
