WARNINGS

• Keep from young children! If two or more are swallowed they can be lethal, by attracting across gut tissue and puncturing it.
• The material is brittle so it can chip or break if magnets crash together. Eye protection advised.
• Magnets can pinch skin and cut clothing.
• For sensitive devices (e.g. credit cards, pacemakers, magnetic recording), keep at a distance where the field is negligible.
