N50 magnets are very powerful and hard to seperate them away,
so when you receive the package,
please be carefull to handle them: don't let them to attract with each other in a long distrance,

or they will be cracked suddenly, as magnets are fragile!

Safety Warning about handling neodymium magnets  
1. Handling strong magnets in a proper manner is necessary to prevent personal injury and property damage, which include magnet damage.  
2. These magnets are not toys. Please do not give neodymium magnets to children under 3 years old. Small magnets pose a choking hazard, and can be lethal if swallowed. In addition, large magnets can easily pinch fingers. So always supervise children when playing with magnets and be sure they are aware of the dangers involved.  
3. Please keep magnets away from people who are wearing pacemakers or other medical devices. These magnets could also damage CRT monitors and TV's.  
 4. It is recommended to wear gloves when handling magnets.  
5. Always handle magnets individually. Do not handle multiple magnets at the same time unless they are widely separated or stacked together.  
 6. When placing magnets together, place a spacing material between them such as a piece of plastic, wood or cardboard so that they are easy to separate when needed.  
 7. Maintain a distance of at least 3 feet from other magnets or magnetically susceptible items when handling the magnets. Pay particular attention to scissors, knives, screw drivers or any other sharp metal objects.  
 8. To separate one magnet from the others, place them on a durable non-metal surface with the magnet-to-be-separated hanging off the edge of the table. Use one hand to firmly hold the other magnets on the table, especially those closest to the magnet being separated. Use the other hand to firmly hold the magnet you are separating. Push it down and away from the other magnets, until a magnetic attraction is no longer felt. Keep the separated magnets a safe distance from each other.
