Features: Super strong rare earth neodymium magnets - they are hard to separate once they get attracted with each other. It's perfect for wind generators, DIY projects, science projects etc. 

Caution: 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.)
