- 21mm diameter x 3.5mm thick
- Each magnet's north pole and south pole are on opposite 21mm diameter faces
- Each magnet can support a steel weight of up to 1kg vertically from the magnetic face when in flush contact with a mild steel surface
- Coated with PTFE to reduce corrosion and provide a water-resistant finish
These Neodymium disc magnets produce a deep enough magnetic field to attract each other through their PTFE coating and material such as fabric. Their special PTFE coating means they are completely sealed and water resistant, making them ideal for closures and clasps on clothing and accessories.
