>>107077759I live in north Europe so not really.
I use "Rexel A3 24 Pocket Clearview Display Book"s to keep my collection in (I have 3 currently). I don't want to frame mine because I prefer to have them all in one place.
I keep the backgrounds that are usually sold with them separate, most of the time they're not the original so no loss there. I also keep a 50gsm A3 sheet of paper in each plastic folder, that way I can have two cels on each side without the backs touching each other. That's the key point I feel, as sometimes the paint will peel off if you have them 'cel on cel'. Or at least that seems to be what happened to this one.
