CYEAH 100 Pack Magentic Label Holder, 1x3 inch C Channel Magentic Labels Holder with Paper Inserts and Clear Plastic Protectors, Magnetic Data Card Holders File Cabinet Labels for Metal Racks Shelves

These are magnetic label holders for metal filing cabinets. Each holder has 2 paper rectangles for labels. I've seen people use label maker labels on these as well. They have a good firm magnet so they stay on the cabinets even if you slam the doors shut. I have 12 old filing cabinets full of music, and filing music required opening every. Single. Drawer, because I didn't know if a song went in drawer 1, 2, or 4! With these labels, I can make that part of the music library a bit more organized and less frustrating. I'm very glad to have these label holding magnetic frames!
