The Amethyst Arouser is amazingly powerful and has switch bottom activation. The power packed dual tongued clitoral arouser is beyond words. It is uniquely designed for maximum stimulation not only with the clit arouser but with the 3" X 1?" shaft with little nubbies as well! It's made of superior quality Crystalessence and uses 2 AAA batteries, not included. Let's go get aroused!
