The UR3 Cock & Balls is no imitation. It's the real thing, molded directly from an erect penis, and then hand painted to insure every detail is true to the original. Now this incredible UR3 Cock & Balls is available for the patented Vac-U-Lock system. A unique locking device that uses the science of a vacuum to hold each piece tightly to one of the 3 available Vac-U-Lock products. The cock is 8" X 2" and the balls are 2 1/4" X 2 3/4" from the base of the penis. Enjoy!
