This product measures 1/4" in diameter and 1/8" 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 surfaces. The pull force of this magnet is 3 lbs. This is a great item for personal projects as well as crafts and closures. It can also be used to help keep objects secured or fastened to any ferrous surface.

Faceshell is a plastic or resin mask that goes underneath a fabric upon which can be placed lenses (eyes) that are magnetically attracted to the magnets in the faceshell. Because the fabric can vary it is important to have a good attraction, especially if dropping the eye piece results in damage to it. This size is EXACTLY the perfect size for drilling a hole and supergluing the magnet into the faceshell and eye piece. The attraction between them is VERY strong. Having 4-6 pairs means you will NOT drop your eye piece and can go on being the best Spider-Man or Deadpool or whatever that you can be. The alternative to getting the 1/16" thickness magnets is NOT recommended unless you are restricted for thickness of material; the thinner magnets just have a higher chance of dropping your eye piece. Fast shipping and the magnets being marked for polarity are excellent bonus features
These little guys are very, very strong. I was really surprised that I had to slide them apart to separate them. These are simply great. I recommend them without reservation.
