>>46604986humidity may still be an issue depending on where you live if you have an open portfolio, though the warping could be much worse if you aren't double sleeving your cards either that or the cold wave fucked up my foils a bit (pic related is warped and I couldn't even tell until I took it out of the binder and outer sleeve and it has been in there for almost two years now)
