As most of you know, the core set came with a handful of boxes in which each player could keep their cards & character sheet. I find these very useful and wonder if they are available to purchase separately?

They're not available, however if you were to gently take one apart, you could scan the white side of it and do your own artwork.

Just a thought on a better use of your money for each player's stuff:

* Gallon zyplock bag and a collectible card album sheet(s).

* Basic action summary sheet (instead of the stack of cards)

I find a ziploc bag to be a quick and easy method. Plus, the bags all lay flat to store in another box.

Look for raaco boxes if you want awesome storage. They fit the different cards perfectly.

You can use this link to create your own box:

You can then download a pdf and modify it in photoshop or something to add your own design and artwork.

Then print it on thick paper.
