playing card box for traveling (designed for Cabo card game)

Designed for the cardgame Cabo with thick 52 cards.

But also for all basic 2.5 x 3.5 inch card games like:

Poker
Uno
Pokemon
...

The box stays securely closed without rubber. However, my primary concept was to design it for travel. Therefore, I created it so that a rubber band or any similar item you have with you can also keep the box together, providing redundancy.

V3 is the clean design
V4 has a larger recess for the elastic band or hair tie and a groove with a better grip
