Exceptional Material: Premium NdFeB coating with strong magnetism provides lasting shine and rust protection, ensuring durability for extended use. Easy to Use: Ensure powerful magnets are separated flat before use; pull magnets from both sides to separate. Keep away from watches, TVs, computer screens, cell phones, credit cards, and other items to avoid demagnetization. Warm Tips: Neodymium magnets possess strong magnetic force but have a brittle texture. If impacted forcefully, they can easily be damaged. Collision with other metal objects (including other magnets) is prohibited. Handle with care!
