This magnet is made of neodymium magnetic material which is the strongest type of permanent magnet currently made. it's 3/4" in diameter and 1/4" thick with the N and S poles on the flat surfaces. The magnet is composed of grade 42 material and are plated in black epoxy for a corrosion resistant finish. The tolerances of all the dimensions are +/-0.01mm with coating.

CMS Magnetics makes the top notch neodymium magnets with the state of the art technology. CMS neodymium magnets are superior to other brand in terms of higher strength, better coating, tighter tolerance and better longevity. All the CMS neodymium magnets are made under ISO 9002 quality systems.

Keep these neodymium magnets away from children under 5 years old. They are not edible and lethal when swallowed.
