Many women prefer a vibrator that is shaped like a penis. The Unilatex Vibrator is shaped like a 20 cm long penis (quite a realistic size). This "realistic" vibrator is made of a silicone material with the same colour tone as skin. The material is flexible but firm, soft enough to feel natural, yet firm enough to transmit the vibrations. This vibrator uses 2 AA batteries. It has a variable speed button on the base.
