I made some deck boxes for 40 card decks of the pokemon trading card game.

They are made for the build and battle boxes, which are used for prerelease events.

We keep the base decks so we can play short games (base game is with 60 cards, these decks only use 40 cards) with (almost) equally strong base decks.

The box has a slot for the trainer tips card, which comes with these boxes, which is mainly used to keep them apart.

Multiple boxes fit in the generic pokemon boxes.

Printed in transparent PETG but other filaments should work too.
