Review on 🔧 SALEX Metal Plates for Magnetic Mount - 32 Pack of Small 0.4" x 0.8" Silver Iron Discs | No Holes - Perfect for Wall, Air Vent Phone Holder, Case, Magnet, Craft | Steel Replacement Set with 3M Adhesive Backing by Richard Koh

I used these on a shelf I made for my daughter so she has room for her Toniebox and Tonies! Their magnetism was incredibly strong and they were extremely easy to attach to a shelf. I appreciate that it comes with an alcohol wipe so I didn't forget to wipe it down before applying. I'll probably end up buying more to put on the shelf at some point! Also, the adhesion is amazing, I'm not sure I'll ever be able to take it off...
