The TomZ 4x4x6 Cuboid is made from a black hard plastic. The idea of this puzzle is to scramble the 6 sides of the cuboid and then return it back to start. One amazing thing about the design is that as the puzzle is scrambled it does not stay in the same shape, so not only do you have to put all of the colors on the right sides, but you also have to bring it back to the correct shape. TomZ 4x4x6 Cuboid was designed by TomZ, from Netherland, and is made by Calvin’s Puzzles who is a manufacturer and wholesaler company based out of Hong Kong that started in 2008.
