NdFeB magnets are short for magnets made of Neodymium Iron Boron which are a lot more advanced and powerful as compared to their ceramic counterparts; these can rightly be termed permanent magnets. Each of these is 10 mm in diameter and come in packs of 20 pieces; these are grayish silver in color and are 4 mm. thick. Being stronger magnets, these can be used to hold heavier objects - either to hold notes on the refrigerator door or hang decorative pieces from metal surfaces. Don't forget to beautify them with our decorative glass gems!
