I saved everything inside the cartridge packaging: warantee, instruction, cardboard insert, and the clear plastic part that held the cartridge. I cut that part down to fit the case. Made a label for each case, on the computer, and after trimming it down inserted it so I can see the name. Placed the cardboard insert in the front cover.
One disadvantage to these boxes, is that they don't fit in the drawer I have the regular Cricut carts in. Have to find a new place to put these. A never-ending search for storage solutions. LOL
