The Rubik's Tower is an irregularly-shaped Rubik's Cube variant. It is a 2x2x4 square prism, and can be thought of as two Pocket Cubes stacked on top of each other.
It can be arranged into many odd shapes during solving. Its construction is complex and you're best off not disassembling it or else you may not be able to put it back together.
This cube does not follow the standard Rubik's colour scheme but it has the Rubik's sticker on at the top.
