Recycled Storage for Slice Cartridges

I bought a Slice machine and a few cartridges, so I was looking for a way to inventory what I have and store the cartridges in easy reach of the machine. This is what I came up with:

I bought these Mary Kay display books at a thrift shop thinking I might make albums out of them. They really work great for this application.  I put the cartridge info sheets in page protectors with  clear double sided tape. Two will fit in each protector. I can see front and back and add to them.  I didn't cut these down so they hang over the edge a tiny bit.  Also I copied these pages for my main inventory book.  Now this can sit on a shelf or my desk and I can flip through it easily to find what I need.  I wanted to keep the cartridges with the book so I used velcro dots to attach the cartridges to the binder cover.

This is so easy to use and everything is right here.  Also if I want to take my Slice to a crop- I fold up the binder and go.  I haven't decorated the cover yet but I will when I decide on colors and design.  I spent about $2.00 on this.  I have an extra binder-- what do you think I should do with it?
