Pure Vibe #70 will give you quite a bumpy ride. Loaded with stimulating ribbing and a rounded ball shaped head. Made of soft silicone with a graduating width. The shaft flares out halfway down for those that like a nice full feeling. The top half is flexible for comfortable movement of the rounded tip, where the vibrations are concentrated. Waterproof for fun in or out of the water. The total length is 8.5 inches with an insertable length of 7.5 inches. Requires 2 AA batteries not included.
