You've never seen anything like this; it's the coolest innovation in butt plugs since they were introduced to the market. Instead of just plugging someone's butt, you can open it and use the incredible tunnel hole that goes all the way through the plug. Besides the unbelievable sensation, the clear version has the added benefit of someone actually able to see right into it. Use your imagination and go wild, or easily insert fingers or lube right through the plug. The Tunnel Plug is made of a blend of silicone and TPR called PF Blend. The Tunnel Butt Plug is safe with water based lubes. This product is not compatible with Latex products. Wash thoroughly with mild soap and water.
