I have gotten in the habit of saving the AOL CDs that come almost weekly. I use some as disposable paint pallets and others are scavenged for thier plastic. I recently received a couple in boxes. They have a flap that is closed by a magnet.
I dug the magnets out before discarding the box.
I'm thinking these little powerful magnets will be good for removable sections, shuttles, etc. Thanks AOL
