Looking for unique wine glass charms? These drink minders feature 5 different vintage illustrations of birds: Cardinals, Bluebirds, French Bird, Owl, and Canaries. Each image is set under a glass cabochon. The glass cabochon is set in an antique brass alloy tray, which is on a silver-tone hoop with a brass bead on each side. The charm itself measures 0.7 inches - the size of a dime. Care: Wipe clean with a damp cloth. Do not submerge in water or put in the dishwasher. Our products are made by hand with care in upstate NY. Thank you for supporting an American business! Fern and Filigree cares about the environment and we donate a portion of our proceeds yearly to organizations that support pollinators through education and research.
