Solid Brass Padlock and 316 Stainless Steel Pin are MADE IN THE USA of brass and steel that were also MADE IN THE USA.  The padlocks and pins are sanded/buffed on a Foredom Lathe, which is MADE IN THE USA.  I also use EJ Wheaton Co. Microcrystalline Wax, which is MADE IN THE USA, to add a protective layer to the bright shiny padlocks.  The shipping envelopes are also MADE IN THE USA.   [Up to 12 padlocks can be keyed alike.]
