Ergonomically designed to fit a woman's body, the Petite Arouse-Her has sensuous smooth curves that lays comfortably over the pubic bone and stimulates the clitoris with multiple vibration modes. It is rechargeable, so you never need to buy batteries, and it's waterproof, so you can use it in the shower or tub. Measuring only 2.8 inches long and 1.8 inches wide and 1 inch thick, it can be easily kept in your purse or slipped into your panty. Made from soft flexible silicone that is durable and hygienically superior to other materials because it is non-porous. Since it is non-porous just a small amount of lubricant makes it super slippery. We recommend a small amount of water based lubricant for maximum stimulation.
