Along with her newly redesigned 100% silicone construction, Mona Wave features ten lip-gnawing modes of synchronized rotation and vibration with fully adjustable speeds for each, worry-free waterproof construction and conveniently rechargeable dual motors. Specially designed, perfectly researched curves and a tapered, deliciously angled head render Mona Wave's shaft comfortably ergonomic, fitting the inner and outer curves of a woman's body to a T while targeting the nerve-ending rich upper vaginal wall and g-spot perfectly. Ranging from deep, steady vibration and rotation to delightful modes of pulsation and toe-curling, teasing roller-coaster like escalation with or without that rhythmic twirling motion, Mona Wave's dual motors power ten breathtaking functions. A simple interface mid-handle controls the modes as well as the intensity- hold the center button for a few seconds to unlock the pleasure. Like Mona's predecessors, the Wave boasts a rechargeable lithium ion battery; a two hour charge reaps approximately 2 hours of use with 90 days standby time. Simply plug the included jack-pin charger into a charge port located on the underside of the base to power up. Mona Wave's velvety smooth medical grade silicone construction, as well as providing a fantastically temperature-receptive, naturally warming experience each and every time, is a hygienically superior, hypoallergenic material that fully encompasses the entire shaft and base. A soft satin storage bag is included, helping to keep her dust and lint free when not in use- store the Mona Wave separately from other silicone and soft toy materials to help keep the silky seamless silicone at its best. As with any silicone toy, always enjoy a good quality water based lube in combination, silicone lubricants should be avoided at all costs. Detailed care instructions, charger, storage bag and warranty card included. Waterproof.
