30 neodymium magnets 1/2 x 1/4 x 1/8 inch ring N48
30 Neodymium Magnets 1/2" OD x 1/4" ID x 1/8 " Thick Ring N48 Rare Earth
Pull Force is approximately 3.06 pounds under ideal conditions These rings are axially magnetized, so the strong North/South poles are on the flat sides.
That makes them easier to stack into a cylinder than to connect side by side. The metal coating is durable, but ALL Neodymium magnets can chip or shatter. If used gently, these magnets can serve you for a lifetime.
Honestly, I like to simply play with them, but these magnets have many practical uses as well. Use them on the fridge. Put them to work in the tool shed.
