Please read the safety information below before you order and use the magnets. By adding this product to your cart and completing purchase, you are acknowledging that you have read the disclaimer below.
Important Safety Warning! Please read the following information from our supplier before ordering and using the magnets.
Disclaimer: Shop4Swag.com and its owners neither assumes nor accepts any liability for damages resulting from the handling or use of magnets. With your purchase, the buyer confirms that you have read and understood the following warnings. The buyer agrees that he/she is responsible for all damages and injuries caused by the magnets, which include personal injuries, property damages and magnet damages.
Neodymium magnets are very strong. Handling them with care is necessary to prevent personal injuries, property damages and magnet damages.
Neodymium magnets are brittle; they can be broken or can splinter in a collision. One should wear gloves and protective glasses when handling these magnets, because splinters and/or spacers could disengage and fly from the magnets.
Normal Neodymium magnets will lose their magnetic properties if heated above 175°F (80° C). The strong magnetic fields of neodymium magnets can damage items such as television, computer monitors, credit cards, bank cards, computers, diskettes and other data carriers, video tapes, mechanical watches, hearing aids, loud speakers and VCRs. Pace-makers may be damaged or switch to “Test Mode” in the presence of a strong magnetic force, if a pace-maker is in use, keep a minimum of 3 feet distance.
You should avoid having constant contact with magnets of any size and keep a distance of at least 3 feet to large magnets.
Children should not be allowed to handle neodymium magnets as they can be dangerous. Small magnets pose a choking hazard and should never be swallowed or inserted into any part of the body.
Under no circumstances should you try to cut, saw or drill the Neodymium magnets! Not only would the magnet break, but the resulting dust from the magnet is very flammable. Neodymium magnets should never be burned, as burning them will create toxic fumes.
