Feature:
1. Powerful Permanent Magnets: Rare earth neodymium magnets have a much higher saturation magnetization than ferrite magnets. It is a representative of strong magnetic materials and has excellent magnetic properties.
2. Numerous Applications: Neodymium magnets are small in size and have strong magnetism. In addition to their applications in industrial manufacturing, they are also widely used in daily life and are ideal magnetic materials.
3. Best Coating Available: A nickel/copper/nickel (i.e. pre-plated nickel + intermediate copper + surface bright nickel) plating combination system is adopted.
4. Easy to use: Easy to replace magnetic substrate. Multiple pieces can be stacked to get stronger magnetism. Widely used in daily life, such as refrigerator magnets or magnetic switches, as well as woodworking, construction, advertising industry, home decoration, packaging and other fields.
Tips:
Neodymium magnets are fragile. Avoid collision and impact during use. Please be careful when separating the magnets.
If the neodymium magnet is damaged, it is easy to splash fragments. Please take protective measures during use and disassembly.
Keep out of reach of children.

Tips:
1. There are many types of magnets, among which Neodymium Magnets are fragile products, please be aware of this before buying. Please be careful when using and avoid the magnets hitting each other, being squeezed, or falling to the ground.
2. For magnets with countersunk holes, do not use too much force when screwing in the screws to prevent the screws from squeezing the magnets and causing damage.
3. The unit of product size is millimeters. During the production of neodymium magnets, there are pickling and other processes that lead to dimensional tolerances in neodymium magnets. This is inevitable. If you cannot accept the tolerance of the product, please do not place an order
