This vibrator may seem similar to what you have seen before - but it is truly different! It features a brand new vibration technology which has never ever been adapted to vibrators before. The patented German invention makes vaginal stimulation an exceptional experience. The entire vagina is being stimulated with wave-like strokes running up and down the shaft. Extra pleasure is added through the ribbed texture shaft. The Waver Groove is 100% waterproof so you can use it in the shower or in the tub for wet fun. Features 3 stimulation levels. Made from TPR. Full size: 28 x 4 cm. (Please order 4 AA batteries separately)
