The gorgeously contoured Nobu Sake features 10 functions of extremely quiet vibration, pulsation and escalation. The tip with the motor stimulates the clitoris, while the shaft seeks the g-spot. The vibration increases with body heat. Made from 100% silicone, it has a plush texture and feels breathtakingly lifelike. Use water-based lubricant, not silicone. Saki is splashproof but not completely waterproof. USB rechargeable. A full charge takes about 6 hours and will power the Saki for about 3 hours of continuous use. Wall plug also included. Length 8.75 in., 5 in. insertable; width 1.5 in. at widest point.
