MoYu 3D Maze 60mm packs a maze puzzle into a palm-sized 60 mm cube. The transparent red shell makes the whole body see-through. It weighs only 65 g, so it slips into a pocket without effort. This version comes from MoYu's budget Cubing Classroom range rather than its speedcube line. The same maze design also exists in solid colours and in a larger 95 mm size.
