The Waterproof Lighted Gem is a glittered powerful, multi-speed massager with a radiant glowing blue light and a ribbed, soft, pliable removable jelly sleeve tip. It measures 6.75 inches in length and 1.25 inches in diameter. Two AA batteries, (not included), provide the multi-speed vibrations and the luminous blue beam. The lighted gem looks especially cool two feet beneath the surface of an unlit pool! All our toys are cleaned and checked before delivery!
