Review on 📱 SALEX 12 Pack Silver Heart Iron Discs - Strong Magnet Plates for Magnetic Mount, Wall & Air Vent Phone Holder, Craft. 3M Adhesive Backing, Steel Stickers Replacement Set by David Lambert

I used these on a shelf I made for my daughter to give her space 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...
