After years of building kits, we all end up with stacks of unused decals. I have found that a semirigid baseball-card holder (sometimes called a trading-card page) is great for decal storage. The material is acid-free and will not attack the decal; you can keep decals from curling and protect them from moisture. You can see what’s inside, and the pages are made to be held in a ringed binder to keep your spares neatly organized.
