Invisible Sun Black Cube Insert (fits Nightside and Book M cards)

The Invisible Sun Black Cube by Monte Cook Games is an amazing product, but for such a voluminous thing it wastes a lot of space. This insert was designed in order to fit all components for the game, all sleeved cards including the additional ones from Book M and Nightside. 

I chose to keep the Hand in its foam padding and just cut it up to a little under half its original size for this model.

Note that there won't be any space for the books left inside the box, but I prefer to store them accessibly on my shelf anyway.
