In the end, I turned to a small cardboard jewelry gift box to hold my depotted messes until I could properly get my hands on some high quality water soluble Elmer's glue, hot glue gun, or super glue to properly attached my depotted eyeshadows. This is not recommended as a portable palette, just some way to keep all your depotted items together so you can happily toss away the plastic drugstore packaging.
Observe, friends.
