The Tristan plug measures 3.5 inches in length with a 1 inch diameter shaft and 1.5 inch diameter head.  This version also has a hole molded into the base in which you can place a removable bullet vibe (included), giving you the option of adding vibration to your play. This plug is designed by nationally known sex expert Tristan Taormino, author of The Ultimate Guide to Anal Sex for Women, The Anal Sex Position Guide, and the DVD "Expert Guide to Anal Sex." The bulbous head and long neck of this toy help it stay in place-- no more pop-outs at embarrassing moments-- and the curved base fits nicely in between your butt cheeks.

Made of 100% silicone by Vixen. The plastic removable bullet vibe takes 3 LR44 batteries (included). In purple or black.
