Some Daily Life Application Show:
1. Disc Magnet is a special goods for delivery, and they have to make special packing before transportation.
2. Antimagnetic Packaging / Neutral Packing / Custom-make Welcome
1. Keep away from pacemakers.
2. Powerful magnets may hurt your fingers.
3. Do not touch for children, parental supervision required.
4. All magnets may be chip and shatter, but if it is used correctly, it can last a lifetime.
5. If the magnet is damaged, please dispose of completely. Shards are still magnetized.
6. If magnet is swallowed, it will be very dangerous.
