If you ever travel to scrap, these boxes are a must have!! They save a ton of spaces versus packing each cart box, and keeps them well protected. The ribbon in my box didn't last very long though, but you don't really need it to keep the overlays in place.
This solved my problem for those Cricut carts with no regular storage box. I like that there's space for the overlays with the carts. Best of all, it holds eight of each in one box which saves space.
