LanLan 3x3 Geary Cube

The LanLan 3x3 Geary Cube resembles an ordinary 3x3 on the outside, but it actually has as complete gear cube mechanism inside the cube. When one layer is turned, the gears inside the cube are rotated, causing other layers to turn as well. The puzzle was produced by LanLan and designed by Oskar van Deventer. It features an official Oskar logo.
