30 Pcs Magnetic Label Holders with Magnetic Data Card Holders with Clear Plastic Protectors for Metal Shelf,Magnetic Racking Labels Shelf Sign and Ticket Holder (3 * 1inch)

I'm helping a charity put stock on metal shelving, but as the stock changes a lot, we can't use sticky labels or anything permanent stuck onto the shelving. These strips solve that problem because they are completely moveable. They have very strong magnets. Each little magnetic strip comes with two pieces of paper inside, plus a see thru plastic protective cover. The paper and plastic cover slide out. The magnetic strips are thick, quality rubberised material. They don't fall off, neither do the paper strips fall out. Of course, you can cut and use your own paper, which means these will last for years. They have solved a huge problem and I very highly recommend them.
