Attention! Danger for children! Choking hazard for small children if magnets are swallowed! Persons under 16 years of age are not allowed to use these magnets. If two or more magnets are swallowed, they may attract each other through the intestinal wall, causing major swelling and life-threatening injuries. Removal of swallowed magnets requires surgical intervention. Keep magnets away from pacemakers. Be careful when handling, especially with larger magnets. There is a risk of skin bruising if the magnets collide. The magnets can also splinter and the individual parts can fly around uncontrollably. Risk of injury! The magnets are difficult to work on because of the brittle material. If you should mechanically work on the magnets nevertheless, please wear appropriate protective clothing (gloves, safety goggles, etc.). During mechanical processing, especially drilling and grinding, there is a risk that the magnetic dust will ignite and burn off at a very high temperature.
