See yourself in a whole new way. The innovative Optix model complements Doc Johnson's Main Squeeze line of masturbators with variable pressure and offers a unique, completely transparent design that knows no bounds for your imagination. Every part of Optix, including the casing, adjustable pleasure features, and the snug, textured ULTRASKYN tunnel, is crystal clear, providing an unparalleled, visually stimulating experience. As always, Main Squeeze is designed to put the power in your hands, with a squeezable grip that allows you to vary the tightness of each stroke and a suction-regulating end cap. The dual hard-shell design also serves as a discreet travel and storage case, keeping Optix as elegant and flawless as the day you opened it.
