Safety instructions:

• Do not place the magnets too close to objects that are sensitive to magnetism (e.g., monitors, televisions, music cassettes, dictation machines, etc.), as there is a risk of irreparable damage!
• Keep magnets away from pacemakers!
• Handle with care, especially the larger magnets. Collision of the magnets can cause skin contusions. The magnets can also splinter, and the fragments can fly around uncontrollably! Danger of injury!
• Due to the brittle material, the magnets are difficult to work with. If you do attempt to machine the magnets, please wear appropriate protective clothing (gloves, safety glasses, etc.). When machining them, especially drilling and grinding, there is a risk that the magnetic dust will ignite and burn at a very high temperature.
