The Mac Ultra-Smooth is built around its defining feature: a thick, extra-long Japanese-style coil handle that gives practitioners real control during insertion and manipulation. The longer handle provides more surface area for your fingers, and the coil design adds the kind of responsive tactile feedback that shorter handles can't deliver. Individual guide tubes included, color-coded for fast size selection.
