Important Safety Information
⚠ Handle with care.
Neodymium magnets are extremely powerful but naturally brittle. If allowed to snap together or collide with metal surfaces, they may chip, crack, or shatter.
For safe handling:
- Keep magnets separated during storage
- Avoid sudden impacts
- Wear eye protection when handling multiple magnets
- Keep away from children
- Keep away from sensitive electronics and magnetic storage devices
