I am concerned that the cards may become damaged over time due to the force required to insert the card. The top rails are loose and the side card slots are very tight, yes it keeps the cards ok, I did a drop test and roll test and it worked, the cards fell out of the slots when they hit the carpet from 3 feet fell and it rolled normally, the tile didn't come up on the roll test, but the cards fell out of the slots. It's more or less a display and a home use-only item. I'm going to get a 16 slot travel wallet and keep the Monster Hunter on my desk.
