Mini marquee storage?

[Kujako]

How are people storing their mini-marquee and other art? Feeling like "in a box" isn't the best option...

To expand on this a bit.

Currently have everything in a plastic folio. Which is fine... but I'd like some sort of protective sleeve for the marquees. Problem is they're larger than small photos, but smaller than normal photos. So having a hard time finding something in the 3.4x5.5 inch range, ideally made from acid free tissue or similar.

Bigger issue are the instruction stickers, which I've just got stored folded in half. Which is starting to cause wear....

I also have them "in a box" ... which for the stickers is an issue.
