A fully-functional and quite festive Christmas tree-shaped Rubik's Cube that also doubles as an ornament to hang on the tree.
This challenging 3x3 puzzle cube has all black thermochromic tiles that temporarily reveal their colors with the heat of your touch and then fade back to black.
This massive version of a 3x3x3 puzzle cube is seven inches large, which means that twisting and turning the colorful rows for speed won't be quite as easy.
