Magnetic Clips, Magnetic Hooks, Magnet Pots are made of magnets and steel iron
Features:
1) Made of iron, steel with sintered ferrite, sintered NdFeB and cast alnico gluing together
2) Sintered ferrite pot magnets and cast alnico pot magnets maintain their magnetic properties under extreme heat conditions, and are ideal for industrial requirements
3) For daily life use as holding magnets
