Can you guarantee safe and secure shipping of products?

Our products always use safe and high quality export packing. We usually use vacuum packing and iron shield packing by air to avoid magnets demagnetization and use wooden pallet or wooden cases that are safe and environmental protection by sea.

How should I store NdFeB magnets?

NdFeB magnets should be stored in a dry, cool place away from heat sources and other magnets. They should also be handled carefully to avoid damage, as they can be brittle and prone to cracking. It is also a good idea to store NdFeB magnets away from electronic devices, as the strong magnetic field of the magnets can interfere with their operation.
