WE handcraft our photo charms, by purchasing the images from a collage artist, then we re size and fit them into the charms and finished them with a hard non-toxic glaze! I hammered a bottle cap for charm in this one. Necklace is a 2.4mm ball chain and is Hand finished, in an antiqued/oxidized patina. This patina is achieved through a natural aging process- no chemicals are used. CHAIN IS 20" LONG I USED A BEAUTIFUL little bird brass charm and I added little REAL watch cog parts.. very cool!!
