A storage box for only the 7th Continent replacement cards. I bought them to save some money on the game. Couldn't find a good way to store them. This is a quick and dirty solution. I'll be improving it as I test it out. Right now you will have a little slop on either side. I will tighten it up in future versions.
The inside dimensions will be roughly 90mmX100mmX150mm. You will need multiple boxes (currently you can fit about half of the unsleeved cards in one box. I have not optimized for length yet. This will fit sleeved or unsleeved cards.
At the moment three boxes will hold everything unsleeved. I sleeved only the action cards and everything still fits in one box.
