Charm Sanskrit characters 'a-hum'

A charm, golden Sanskrit letter "A" on the front and "Hum" on the back of a metal circular frame are encased in transparent resin. (Diameter: 30mm, Thickness: 3mm, Weight: 6g) About the gold letters on both sides (frond and back): Two types are available: 'normal' using mirror powder for nail art, and 'special' using pure gold leaf from Kanazawa. (3rd and 4th photos, left side is special, right side is normal.) Sanskrit "A": The first sound that occurs naturally when the mouth is opened. Sanskrit "Hum": The last sound produced when the mouth is closed. In other words, Sanskrit "A-Hum" represents the beginning and the end of all things.
