DO NOT let magnets contact each other or any magnetic surface. ;tick. This can cause the magnets to break! We never compromise on quality. and all of our products are subject to performance tests at; using a traction and compression machine processed by computer. The system accurately measures the weight a magnet can hold when pulled. vertically and the quantity The pull a magnet can exert when there is space or non-magnetic material between the magnet and the material it applies to attract. By using the best technology, we make sure our customers always get the right magnet. for their application. 1. Hold on to away from pacemakers. 2. Strong magnets can hurt your fingers. 3. All magnets can chip and break, but if used correctly can last a lifetime. 4. If damaged, discard completely. The fragments are still magnetized. If swallowed, magnets can inflict serious damage.
