The material mix of medical grade plastics and surgical steel makes Tristan especially light weight, so that one can walk around and enjoy the greatest freedom of movement even when Tristan is inserted. The probe also stands out thanks to its ergonomic design, which makes the usage especially comfortable, soft and continuous. Tristan has especially big contact areas made of surgical steel, so that the electrical impulses are being transmitted very comfortably and continuously. Moreover the separation between the plus- and the minus-pole is made very early, so that the stimulation can be felt soon after insertion. Packaged to appeal to a mainstream customer, Mystim Tristan is designed for use with the Mystim Tension Lover Kit (#A00400). Coming from the medical field, each vaginal/anal probe is appealing because the lightweight bodysafe plastic and surgical steel stays in place even if the wearer is moving about, and the ergonomic design makes the transmission of impulses especially soft, continuous, and intense.
