Excellent magnetic coating: triple nickel copper nickel (NiCuNi) coating;this gives the viscous magnet a smooth surface to better withstand external stress and intervention.Durable and: Manufactured with science and technology in accordance with ISO 9001 quality system.Powerful magnets: The grip is amazing, and the attraction of each magnet is not less than 3.1 kilograms, which can be directly touched and pulled directly.Paired magnetization: These are self-adhesive magnets with half the axial magnetization, and their bonding surfaces are located at the magnetic south pole and the magnetic north pole!For example, if you need to magnetically connect 2 viscous magnets together, this is very useful!Versatility: It has a wide range of uses, from simply putting items on the refrigerator to decorative and creative items used for craft activities, most industrial, household, scientific and office uses.Attractiveness and adhesion are strong and high.Be careful, this is not a toy!
