Each initial is hand formed out of thick aluminum wire, hammered and then polished to shiny finish. Aluminum does not tarnish, so you will be able to enjoy this piece for years to come! These charms also make great gift tags to tie to your packaged gifts. I make a generous sized bale so that you can slide your charm over your favorite chain! Each initial is approximately between 1 1/8” - 1 1/2” tall except the “Y” which is approximately 2” tall.
