You will receive twenty-five logo tags which are oxidized sterling silver plated brass. They measure 17x7mm and they have a 1mm hole at the top. You can use them as a logo tag or glue them to the back of a stamping with no hole. One way to engrave these tags is with a Dremel tool and engraving attachment (Dremel 9924 Engraver Carbide Point Bit) which can be found at any Home Depot, Lowe's or almost any hardware store. #A333
