Block Ferrite

These are very powerful magnets. I ordered them in to put address numbers on them for my mailbox. They are a perfect size for the numbers I ordered in. Now when I change covers I can put these on for my mailbox numbers. Other magnets were questionable if they would hold through the mailbox cover. No problem with these! They were a good price for such powerful magnets. I was concerned about the thickness of them but love that it gives our address numbers a three dimensional look. They are supposed to be weather resistant and not rust. Time will verify that. Very happy with them.

Very strong. Thank you for a great magnet.

I used these magnets to sew into the hem of my parrot cage cover. They are extremely strong. This is my second purchase .

These magnets are strong and are great for my intended use, (attaching mosquito netting to my van hatch). However, as others have stated, they are brittle. Just the force of two coming together is enough force to chip them. I didn't want the magnets to directly contact my van's paint, so I wrap them in duct tape- which works perfectly as I create a small pull tab on each one. These are very strong, and I am pleased with them.

These are fantastic for handing note pads, cards, pens, all kinds of stuff on any metal surface. Bought one set, and then another. They support a lot of weight.

Magnets will “fly” from across the room. Excellent product! My single burner camping stove requires 8.8 ounce bottle of butane. (Metal bottle is size of shaving cream container.). Bottle is securely placed inside stove, but door is not latched.). Magnets keep door tight and secure. Did I say strong. Great value for money.

I have a vintage stove with a door that had a broken spring and wouldn’t stay open. I used these magnets to keep the door closed and they work great! I’m so pleased that I didn’t have to do anything to interfere with the integrity of the stove. The magnets are strong but not so strong that the door is hard to open. They’re perfect!

These work nice.
