It is a box!,
Verified Purchase(What's this?)
This review is from: BCW 800 Count- Corrugated Cardboard Storage Box - Baseball, Football, Basketball, Hockey, Nascar, Sportscards, Gaming & Trading Cards Collecting Supplies (Misc.)
I got this to store cards in. It came pre-folded so that I didn't have to do any work at all. I just opened it up and put my cards in it.
It is also white and non-glossy, so you can write on it.
