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

Quality magnets and good size too. I ended up using them on board and also on the fridge and some furniture for the kids. I would recommend for sure.

Good for labeling my toolbox

These magnets have helped us stay organized at the race track and keep everything on schedule. You could use for practically anything. Great quality.

Work well. Easy to print your own inserts or hand write on the inserts provided. Magnets stick just fine to everything I’ve stuck them to.

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.
