Previously they were stored one on top of each other in 2 piles in a very narrow place. I would have to pull out the front pile to access the back pile or to even read the side of the case.
So I have gone from this:

To this, a neat & compact way to store and carry:
I will arrange the books in alphabetical order with a small tag attached to the spine for ease of identification. The overlays are stored in the book.
The cartridges are held in place by velcro dots applied ot the back of the cartridge & the lid of the box.
The box measures approximately 13 1/2" x 9" x 6 1/2". There is room for more books and an extra layer of cartridges could easily be added.
