The Makizume Robo Ingrown Toenail Fixer is a simple device. It consist of two clamps and a threaded press. Slip the clamps around the edges of a toenail--preferably someone else’s--then turn the center press until it forces the edges of the toenail to spring up. Soak the foot in water for a long time, then dry. It’s the perfect party game!
