The One Touch Enhancer is made of hygienically superior silicone and includes a vibrating stimulator. The textured enhancer ring is stretchy to fit most sizes and the bullet sleeve is nubbed. The removable 1.75in x .5in micro-bullet has an on/off button for easy activation. The micro-bullet requires 2 cell size batteries (4 included) to provide powerful vibrations. Feel the one and only touch of this enhancer!
