Very large and fairly heavy ferrite ring magnet. Each magnet weighs approx. 280 grams.

There are many advantages to ferrite magnets: they withstand both outdoor use and temperatures from -40 to +250 degrees Celcius.

This is a quite strong ferrite magnets, and it is not a toy. Careless use may cause the magnet to crack as the magnets are raw and not wrapped, so avoid shocks and impacts. And keep hands and fingers safe!

NB! It has no significant effect on the magnet's strength and magnetic abilities in general if small flakes are knocked off it. 

Processing of magnets may only be done with special tools, designed for magnets.
