Magnetic Steelbook Wall Mount

Cut magnetic paper (8.5x11 flexible magnet sheets) into quarters, attach each piece to the wall with two 3M Command strips, and stick your steelbooks on. Space them at least 1 inch apart so you can pull them off easily. The magnetic paper's own adhesive backing is unreliable, so Command strips are the move. This setup has survived three apartments over six years for one r/Steelbooks user, and when you move you just pull the Command strips and save the paper. No stud finder needed, no holes in the wall, fully renter-friendly.
