Anyone knows how I can avoid this kind of damage to these soft cover binders?
I live in a very humid region, so maybe that's what caused it? I've never put anything on top of the binder and also never creased the cover. I keep it laying down on a shelf inside a wardrobe. Should I keep it vertically instead?
I apprecciate any insights on this, since I just bought a brand new one and wouldn't want it to have the same fate.
