"4-H Mom" is hand stamped onto a 1.25" food grade aluminum washer. A four leaf clover charm hangs from an 18" sterling silver plated snake chain. Aluminum is very light weight but super sturdy metal. It will never rust, tarnish or turn color. Hypoallergenic. Hand stamping is done by hand one letter at a time with a hammer and a shank. Alignment, spacing and depth may vary which is what gives each piece an individual charm.
