This clear butt plug has a hollow tunnel through the middle allowing easy access to the anus when it is inserted. The one-inch opening will accommodate fingers, lube, or vibrators and gives a clear view into the anus. It is made in the USA from Sil-A-Gel, a PVC material with antibacterial properties. It has an overall length of just over four and a half inches with just under four inches being insertable. Furthermore, it has a width of just over two and a half inches in diameter. The flat base makes it comfortable to wear. The material is pliable yet firm enough to not collapse. It is safe to use with all personal lubricants.
