The Gear Change I is made from a high quality clear red plastic that comes with do-it-yourself stickers. The object of this puzzle is to scramble up all 12 sides and then return it so that each side only has one color on it. The gear system of this puzzle makes solving it an extra challenge. This puzzle is a little easier than the Gear Change II, and is one of many great puzzles from LanLan.
