These files are for a better way to organize your standard-sized cards. The container I used is a scrapbook page container (12"x12") that my wife bought from Hobby Lobby. I included a few different-length containers to accommodate different-sized containers. My container fit x3 of the 151.5 trays, x2 of the 171.5 trays, and one of the 151.5. The trays are wide enough to fit the cardboard boxes that the pokemon card decks come in. Also, it will fit cards in sleeves.
The author marked this model as their own original creation.
