Warning:
1. Magnetic field strength: It depends on the grade of the magnets and specifications of the shape. Simply think that the higher the grade level, the higher the surface magnetic field, which is wrong! The premise is the same specifications, the higher the grade, the higher the surface magnetic field!( For example, N35 D3 * 10 table magnetic> N50 d30 * 2.)
2. The strength of the suction: The higher the magnetic table that the greater the unit area of the suction! Suction = Unit of surface magnetic force * unit of area. Therefore, we can not simply think that the magnetic pole of the magnetic pole must be large! For example, N50 D3 * 10 suction <N33 10 * 5 (Although N50 D3 * 10 > N33 10 * 5).
3.The unit of NdFeB magnetic is mm, so please confirm the the size when you purchase, so as not to take the wrong goods.
4. NdFeB magnetic is fragile, especially the thin, long, but also pay attention to the operation,please carefully shift staggered, do not break directly, separated to maintain a certain distance.
5. Strong magnets should keep away from ironware and some easily magnetized iron products, such as monitors, bank cards,computers, televisions, mobile phones and others.
6. Strong magnets should be stored in a dry, heated environment, and need to use of plastic, wood, cardboard, foam to separated and wrapped.
7.Magnets might be interested in water meter ,Electric meter, gas meter and some metering equipment exist some inaccurate affect
(Such as : if magnets placed near the meter, the meter will slow down)
 
This is a seriously powerful magnet and it is totally unsuitable for children!!!
 
Note: Be careful fragile and clip hand, placed in a dry place, stored at room temperature!
 
Notice: 
1. Please allow a bit error due to manual measurement. please make sure you do not mind before you bid.
2. The color may have different as the difference display, pls understand.
