This product measures 5/16" in diameter and 1/16" in thickness and is made of a grade N52 neodymium, iron, and boron magnetic alloy blend. This magnetic blend is patent licensed and made under the ISO 9001 quality systems. They are plated in a nickel-copper-nickel coating for a shiny corrosion-resistant finish. The North and South poles are on the flat sides. The pull force of this magnet is 2.1 lbs. This is a great item for use in personal projects as well as for crafts and closures and can also be used to help keep objects secured or fastened to any ferrous surface.

I ordered 100 of these, then realized I needed more (because I miscounted how many things I wanted to put them on) and ordered another 200. The 200 arrived first via UPS in just a couple of days and then the 100 arrived via USPS a couple of days later. With the 200 in the four stacks of 50 that they arrived in, I was able to hold up the ball of a trailer hitch and carry it around while only holding the magnets. I don't know how much more they can hold, but they did that with no problems and since I'm using them for magnetic pins that was all I needed to verify.
I was quite surprised and pleased when my minuscule order from CMS arrived so quickly. Not only was the service fast but the pricing extremely competitive!
