Our Neodymium magnets are extremely strong, never loses their strenght. The strength, however, is reduce by half after 40,000 years (!)If you need any particular sizes that we do not have in store, then please contact us and we will get back to you.Warning!While it's fun to play with magnets, our most powerful magnets are not "toys". If you get your fingers or other body parts caught between the magnet and for example, a piece of iron, it can cause substantial damage!The magnets are not completely insensitive to shock or impact. If you "drop" one of our magnets against a piece of iron or accidentally merge two magnets, it can damage the magnets.They can easily erase old floppy disc, videotapes, credit cards etc!
