TRYMAG Ferrite Big Ring Magnet, Round Ceramic Magnets with Hole, OD2.36 x ID1.26 x 10mm, Large Magnets Heavy Duty for DIY, Science Projects Industria-Pack of 2

Super strong and they work as advertised. They are good magnets in my opinion.

Use them as door stop . Works great

Good quality magnets !

Vary strong👍🏼👍🏼👍🏼

For what I bought them for they just don't hold. I used all of them to hold a small, flat sided trash can to my fridge in my camper. Idk if the metal it's adhered to needs to be thicker. I'll find another use for them.

Works great

I put plastic shower curtains on the outside of my gazebo during the winter to keep the heat in. I was using these to hold the shower curtains to the gazebo screens, one on each side. However, gusts of wind would blow hard enough these would fly off, sometimes 4 or 5 feet away. They do make great fidget toys.

Works perfect. Great buy!

excellent for those little experiments with the kids i would like to have more to my collection so that the end result make a real impression

Ok
