This case is ment to be used for Magic the gathering sleeved cards.

It holds up to 100 sleeved Cards, token cards, dices and markers.

The locking mechanism was planned to be used with a 2,3mm -2,5mm in diameter leather string. You can also print the “without lock” version of the case and just use a rubber band to secure everything in place.

If you have a good idea for a better and more reliable locking mechanism let me know :)
