I handstamp an aluminum bar charm (1 and 1/4 inch long by 1/4 inch wide) and handstamp it with the Greek Letters Phi Sigma Sigma. The letters are handstamped so expect some slight variation as it is handmade, but that is what makes it charming. It comes with an approximately 18 inch stainless steel link chain. Both aluminum and stainless steel are non-tarnish, so it will stay looking great. A perfect big little gift! Officially licensed, we are the manufacturer and licensee. Handmade in the USA. We make this necklace in 27 national groups.
