See yourself in a whole new way. The innovative Optix model joins Doc Johnsons Main Squeeze line of variable-pressure hard case masturbators and features a unique completely transparent design that leaves nothing to the imagination. Each part of Optix including the case, adjustable pleasure features, and tight, textured ULTRASKYN tunnel is crystal clear, offering an unmatched visually stimulating experience. As always, Main Squeeze is designed to put the power in your hands, featuring a squeezable grip that lets you vary the tightness of each stroke and a suction-adjusting end cap. The double-cap hardshell design doubles as a discreet travel and storage case, keeping Optix as sleek and immaculate as the day you opened it.
