THESE MAGNETS ARE NOT FOR THE FAINT-HEARTED! They are seriously powerful magnets and totally unsuitable for children. All magnets are brittle; do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Serious risk of injury if skin or fingers are trapped between magnet and steel or two magnets.

It does not take account of manufacturing tolerances, plating, plating thickness or variances in a mild steel plate. The vertical hold is based upon the calculated pull and is, therefore, only for guidance. Factors such as paint thickness, plasticised surfaces, movement and vibration are not taken into account. These are all ideal for a large range of science and DIY uses.

If you need to use an adhesive, we recommend using something that will bind to metal and whatever surface you want to glue the magnet to. WARNING: THESE MAGNETS ARE COMPLETELY UNSUITABLE FOR CHILDREN AND THESE MAGNETS ARE NOT TOYS. Do not allow these magnets to jump together or to an iron/steel surface - they will break, crack, chip or shatter. Serious risk of soft tissue injury if skin is trapped between magnets or magnet and steel.
