Review of Magcraft NSN0548 1/4-Inch by 1/4-Inch Rare Earth Cylinder Magnets, 20-Count

They deliver what they offer.

I use them as a distraction while I'm thinking. Add in a handful of small ball bearings and a few steel rods and you have a small sculpture set. I sewed a few of them into a canvas tool bag and they hold loose screws and small metal parts in place. You can find nails behind drywall with these as well.

Everybody should have a few magnets in the house.
