no chamfer no bullshit

stronger attraction than other ring magnets i had. I use a bunch of these to tape a whole bunch of crap to my fridge door. Even the most aggressive midnight snacks don't bother them. They don't have a bevel and appear to be a little thinner so if there isn't a sheet of paper or whatever underneath they can push them out a little more gently than a regular ring magnet.

Pros
  • ceramic magnets
Cons
  • high price

Exactly 1 1/4 inches in diameter. The center hole is 3/8 inch in diameter. Not as strong as expected.

They are exactly 1 1/4 inches wide. Center 3/8" across. This magnet will hold your new hole punch securely to your fridge. An old vintage hole punch is a bit heavy for this magnet. It will stick, but is likely to fall off when the fridge door is closed. Connect two magnets together with each other and they will be very strong. So far there have been no problems breaking with them.

Pros
  • Industrial & Scientific
Cons
  • I don't remember but there was something

Great for science classes but break and chip easily.

These strong magnets are great for science classes. The hole is big enough for a pencil to allow the magnets to levitate. My only complaint is that they break easily! 24 students used them for 20 minutes just trying to run the magnet to see if the magnet's attraction would go through their desk (pass), if they could pass the paperclip and transfer the magnet's attraction to the paperclips , without the magnet. Nothing caused the magnets to fall off, and yet three groups came back to me with…

Pros
  • Material Handling Materials
Cons
  • Unsafe
