This is a traditional hand made Navajo silver stamp. I have been making and using stamps for more then 50 years if you take care of this stamp it should last you the rest of your life. This stamp is 4/10 of a inch wide and 3 1/10 inches long. Remember always anneal your silver before stamping it wear safety glasses and don`t hit your finger. The thicker your silver the better any stamp will work.
