This auction is for one pair of SINGLE COBALT MAGNETS - .430 TALL X .380 LONG X .075 THICK. They are fully magnetized and very strong. When honing to size, try removing the "hone dust" with a garden hose with a spray nozzle. It takes most if not all of the dust out and cuts down dramatically on the tedious task of taking it out with the magnet puddy. Be sure to hange on to the can carefully or it could fly away. That wouldn't be too good for the magnets.Buyer is responsible for shipping cost of $2.75 domestically in the United States. Will ship international at $6.80 shipping cost. .
