I finally have what I believe to be all of the CubeTwist bandaged puzzles (all full size and all black body):
Back row (all from left to right):
B355
B445
B455
5x5x5 Maze Cube
5x5x5 Bandaged Centers Cube
5x5x5 Burr Cube
B345

Second row:
4x4x4 AI Cube
4x4x4 Bandaged Revenge Cube
B244
B443
B234
B334
4x4x4 Burr Cube

Third row:
3x3x3 3-Slices Cube
Bicube (the original Bandaged Cube)
3x3x3 Big Block Cube
3x3x3 Bandaged 3 Cube
3x3x3 Fuse Cube
3x3x3 2-Bar Cube

Front row:
Void Bicube
Void Bandaged 3 Cube
Bandaged 2x2x2
Bandaged Pyraminx

I did not buy the 4x4x4 and 5x5x5 Wall Cubes because they are the same as the respective Burr Cubes. Also, the leaflet that comes with these shows a B335 (B3x3x5) but I'm pretty much convinced that it was never made and sold. See viewtopic.php?f=4&t=23194&start=0

Nice , and those that I can see, that are missing, are the keychains

Wow. Nice.

The collective noun for these is a "hospital" I should think

If you were to buy only one or two of these type, which would be the best examples that balance fun with challenge?
