This is a lot of 10 really strong Neodymium Iron Boron Magnets. The picture shown is two of these magnets supporting 98 thru my index finger. These magnets are 1/2 inch round in diameter by 1/10 inch thick. They are rated at over 13,000 Gauss each and the set of 10 has a combined pull force of over 50 pounds. Due to the force of these magnets they must be shipped separately in their own box, so shipping can not be combined or reduced on this item. Most magnetic therapy magnets are in the 800 Gauss range, these are over 16 times stronger and can be affixed to the body with surgical tape or a band-aid. This item is great if you are looking for a magnetic healing magnet or just a set fun strong magnets to play with. Caution, do not put these near credit cards, flash drives or any magnetic media unless you want it erased. If you need any more details about this item, just ask.
