Carl's Bubbloid 4x4x5

The Carl's Bubbloid 4x4x5 is a shape-preserving 4x4x5 corner-turning cuboid developed by Carl Hoff, David Ang, and Calvin's Puzzles. It has a very sturdy, substantial feel, and it features the Calvin's and Carl Logo.

Please be advised that the puzzle as it is shipped from the manufacturer does not have much corner-cutting ability, although it does turn well when it is aligned properly. The manufacturer has noted that removing the springs from the corners will improve the corner-cutting on this puzzle.
