Constructive Destruction of a cp tray

My constructive destruction on fabercastell polychromos packing.

choose 2 tray to cut their edges. These two tray that edges being cut away, were placed as the bottom and middle layer. I do nothing on the last tray and it will be placed as the top layer.

3 tray can be placed on top of each another.

Goal achieved : half space saved and things keep tidy.

shortage: packing being damaged for my own easier usage.
