Not content with giving us one 3x3x3 cube in a box puzzle (Belt Cube 3), Osanori and Pelikan have released another, even more difficult version, rather descriptively named W-Windows. The name clearly comes from the fact that it has a nice cubic box with 2 windows in it (not the usual diagonally opposite holes) and two of the pieces have a definite W shape to them. Make with combinations of either Apple and Ovangkol or Oak and Wenge woods.
