Get off responsibly with the Earth Angel vibrator, the most eco-friendly toy on the planet. We're thrilled to introduce the first sex toy to contain completely green technology. It's manually chargeable: just crank the key (which fits neatly into the base) for four minutes, and you've got a half an hour or more of vibration (or crank eight minutes for an hour) at three distinct, ultra-quiet speeds. All elements of the Earth Angel are made from recycled plastics, from the mechanical parts to the toy packaging-this is truly the perfect gift for travelers and eco-minded/thrifty folks who'd rather not buy batteries. Please note: Earth Angel can be charged alternately with a 5-volt charger (not included) for those who are unable to perform the continuous cranking motion. Black version also includes soft, textured TPE sleeve and USB cord for charging.
