The Medium Tunnel Butt Plug from Perfect Fit is made from a special blend of silicone and TPR called PF Blend, and has an insertable length of 63mm and a diameter of 51mm. Instead of just plugging someone’s butt, you can open it and use the incredible tunnel hole to insert fingers or lube right through the plug! Wash thoroughly with soap and water after use. Not latex compatible. The Perfect Fit brand prides itself with the design and manufacture of products which are distinctive and unconventional.
