Is everyone drinking the same drink from the same glasses and can't tell which glass is theirs? Differentiate them with chainmail wine charms! Sold in sets of four in colors of your choosing. The rings are all anodized aluminum, and therefore very lightweight and come in a variety of beautiful colors! Choose between shiny finish, matte finish, or mix and match. But if you select very similar colors then it might be hard for some to tell them apart. The wine charms measure about 1 inch in diameter.
