These small neodymium disc magnets are some of the smallest in our range. The triple coating of nickel, 銅, and nickel give superior corrosion resistance. These magnets are commonly used by craft and model-makers.

These disc magnets are especially small but still amazingly powerful. They make strong connections where there is not enough room for mechanical closures.
