Strong magnets is made of rare earth at high temperature, and it is impossible to guarantee 100% perfection. Its small flaws will not affect its performance and use.3: Strong magnets should keep away from ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions and mobile phones4:Prohibit contact and use by children under 8 years old, prevent children from swallowingCaution: strong magnets are brittle; strong magnet could pinch your fingers badly; if you allow two magnets attract together, it may cracks and the chips could hurt your eyes(The pull force was tested at 20 Celsius degree, on a polished iron plate with a thickness of 20 mm. The magnet was deducted vertically. A difference of up to -10% compared to the specified value is possible in exceptional cases.)Neodymium magnets Usages
