Notes:
1. The magnet is not iron. The raw material is rare earth neodymium iron boron. It is fragile and cannot be bumped. Because it has suction, it will be sucked up when it is not noticed, and it may be broken.So please be careful to avoid slam together.
2. When the strong magnetism is attracted and separated from other irons, be careful not to impact, otherwise it is easy to cause damage or pinching fingers;
3. NdFeB strong magnetic materials are hard, brittle, and have a strong magnetic field, so they should be taken lightly, especially for large sizes and thin slices.
4. It is recommended to push and stagger the strong magnetism, and do not pry hard, otherwise it is easy to cause missing corners;
5. Never place neodymium magnets near electronics, strong magnets should be kept away from monitors, bank cards, computers, TVs, mobile phones, etc.
6. Neodymium magnets will lose their magnetic properties if heated above 80°C/176°F.
Warnings & Safety Information:
WARNING 1: Keep Out Of Reach Of Children Under 14 Years Of Age.Older children should handle them only under adult supervision, and wearing proper safety equipment.
WARNING 2: Strong magnets can pose a serious pinch hazard due to their attractive force on each other and to any metal object containing iron.So please stay focused and take safety precautions, such as wearing safety goggles, when handling large magnets.
WARNING 3: If magnet damaged please dispose of shards completely. They are still magnetized and will cause serious problem if swallowed by children.
