The Mystim Curving Curt is an innovative bi-polar electrosex prostate stimulator made of 100% medical grade silicone. Its curved c-shape, the handy grip ring and of course Mystimâ  s brand new Flex & Stay techology make Curving Curt exitingly intense and individual at once. Thanks to Flex & Stay you can bend Curving Curt in whatever form you desire, the toy will keep this form. Length: 130mm. Diameter: min. 17mm max. 33mm. Material: medical grade platinum silicone. You will require an e-stim device - like the Mystim Tension Lover (MY46000), or the Mystim Pure Vibes (MY46010) - to activate the poles.
