These dangle earrings are created from a LUFKIN RULE COMPANY ruler No.1176. They are made of steel and have a sterling silver tubing and ear wire. They have a protective coating on them to prevent them from rust. Just like any amazing tool...the more you use the less it will rust/tarnish.
**These are STEEL. They have a protective coating on them that will last years. This protection will take any length of time, and depends on the activity of the wearer, but needs to be noted, since they are NOT waterproof for all of eternity. Never wear your earrings in the water.
