This product measures 1" in diameter and 1" 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 101.6 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.

In my first order from CMS, I ordered an N42 sphere that arrived damaged (was clearly damaged when it was packed) and this N52 cylinder. My brother placed an order at the same time (also his first) for the same two magnets - his sphere was perfect, but his cylinder was damaged. So, I think that quality is a risk when ordering from them.
That said, my cylinder looks and works great. Mine arrived with more of a matte finish versus the shiny surface shown in the pictures, and I'm happy. I like the matte finish better.
I bought mine to try it out in a Feel Flux (a copper cylinder), and it works fantastically well. The Feel Flux comes with an N52 sphere that works great, but this cylinder takes even longer to pass through the copper. A great purchase for me.
So, yeah - not sure if I'll order from them again because of the quality issues, but both magnets that I ordered are the correct size and sure seem to be of the correct strength. Price was good, too.
