So I've been trying to find a good way to store all my cards. The pilot cards are easily stored in a deckbox, but I was wondering where to store the mini ones (sleeved) and then I saw this at my FLGS.

It's a side-load horizontal deck box, which will fit the upgrade/damage cards perfectly upright, like a normal deckbox.

Here is mine with all my cards in (they're loose, because of new sleeve, but can easily fit another 1/3 of what I have, which is one of everything except the huge ships and bomber and lambda)

Nice find!

I use an Ultra Pro Dual box like this one:

Its for normal sized cards, but one compartment is side on. I scored and folded one of the dividers so the side-on compartment holds 2 x 60 upgrade/damage cards in sleeves. My pilot cards sit in the upright compartment (holds 60). I think there is a bigger version of this box too.

I use some of the little plastic bags that come with the models. The second-smallest ones are just the right size.
