Availey. 60 Pack Magnetic 'C' Channel Label Holders for Metal Racks and Shelves with Protective Films and Replacement Strips 3" x 1"

these are strong magnetic IF you pay attention to a couple of things. Worked well on metal tool box, worked well if flatten and pressed down on tool box, worked well if width allows item to be completely flush on surface, not as as strong on wire racks where wire gaps don't allow enough magnetic connect points.

I am loving these magnets. I have metal file bins and in/out boxes that have 5-10 slots. I labeled all of the slots. The magnets are rubber and often have to be bent straight, but they work great. I print labels on my P Touch and then stick them to the paper that comes with the labels. The maximum number of letters I can get on one is 13-14, depending on the number of 'I" that are in the word. Mississippi takes up less space than other 11-letter words. The magnets are holding just fine after a couple days.

Love them. Helped organize my tool box.

Quality item that I am using to label tool drawers in a workshop.

I have some wire frame shelving at home in my kid's playroom. I wanted to add some labels to the shelving, but while most wire frame shelving labels are for 1.25" wire shelves, my wire shelves were just 1" tall. So I needed to find labels that were just one inch tall and which attached to wire frame shelves. These magnetic ones were perfect. They are exactly one inch tall. They fit my wire shelves and might fit the standard 1.25" shelves as well. You can see up close pictures of them on the shelves. They don't look bad. And I used a label maker to place labels inside of them. The only down side to these is that the strength of the magnets is very weak. It barely works for what I want. They can very easily come off by accident. I think there might be better solutions out there. I like the idea of them being magnetic, though. If it's too weak for you, maybe you can purchase some adhesive backed magnets to attach to these. I tried that with these, and the adhesive backed magnetic sheets I used are maybe 50% stronger, but still not quite as strong as I really want. I'm not using those extra magnets, though. Not yet. I might eventually if my kid starts knocking those off the shelves by accident all the time. Would I get these again? Probably. Unless I happen to see another product out there that had reviews stating better magnet strength. What I really like about these is that if you want to move them around, it's really easy to do. Whereas, other types of labels are going require attaching with adhesive or using some mechanical method of attaching them, which means you do have some extra hassle.
