Magnetic puspin is generally constructed by a strong Neodymium magnet in a shaped plastic or steel casing. Though it is in a small size, actually it is with unbelievable strong holding power
The rare earth magnets we use are made from Neodymium, making them among the strongest permanent magnets available. Our new and improved Pushpin Magnets are now even stronger with more holding power than ever. So post or hang things on your refrigerator with confidence. Post or hang things in your office cubicle. A little fabric covering is no problem for these office magnets. They are easy to grab on to and just like push pins they are small so they won't cover up your stuff. These rare earth Pushpin Magnets are simply incredible. They work like tacks for metal with 10 to 20 times more holding power than the average refrigerator magnet. Nothing you have today compares!
