These small silver Winged Heart charms come from a company in California called TierraCast. They are 100% made in the USA and are nickel free! This beautiful Winged Heart is made using Cadmium & Lead free Pewter and is plated in .999 Britannia Fine Silver. This heart is perfect for hanging from a Ball Stud Ring or O-ring on a Day Collar, but not from a Dee Ring or it will hang the wrong way. The dimensions on the winged heart are 15 mm wide x 17.75 mm high and the internal diameter of the loop is 2mm. I include a small silver jump ring when ordering this charm. This little Winged Heart charm is perfect for a Princess DDlg collar.
