Product Description
Rare earth magnets are the strongest type of permanent magnet currently made. They are amazingly powerful for their size and have innumerable uses. These disc magnets are 0.375 inch (9.5mm) diameter and 0.063 inch (1.6mm) thick. They are magnetized through the thickness. They are composed of grade 40 neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Their individual pull force is approximately 2 lbs. Max Working Temperature - 176 F (80 C). Magnets may chip and crack if allowed to snap together.

 Great item great seller September 9, 2008
Magnets work as advertised; nice and strong and compact. They are however a bit brittle but being careful to not let them snap together you shouldn't have any issues. Seller is fast.
 Great Magnets! Perfect for Craft Projects! December 14, 2007
These are great for making your own craft projects! I use them to turn small figurines into refrigerator magnets! Very good!

Neodymium-Iron-Boron rare earth magnet: 3/8" wafers... The north and south poles are through an axis of the "cylinder", as you would expect. This means they want to form a long "rod". It is almost impossible to push them north to north, or south to south pole (probably 10-15 lbs of force). When you play with them like this, they actually start to get hot from the magnetic "friction. You can make one of them "dance" and stand on edge at about 6" away. Don't throw them, or let them "snap" back into the stack, these wafers are very brittle (I've already cracked one). They seem to be chrystaline or cast metal, but chromed.
