I'd really be interested in how everybody stores their decals these days.
In the past I use two or three ringed note books with clear sleeves. I then place the decals sheet inside sandwiched between tracing paper. I can get a good idea what I'm looking at thru the tracing paper without removing the sheet from the sleeve. Plus each sheet will hold two 1/32 scale sheets. Sometimes four 1/48th scale sheets. What bothers me is that they are not completely air tight. Be interested in your thoughts and ideas.
