Here are 3 buttons that coordinate. They are all open work gold tone metal with black and white enamel decoration. They remind me if the yin yang motif. They have self shank backs. Diameters are 5/8, 6/8, and 7/8 inches.
Please note that button purchases can be combined to save on shipping. At least 3 lots,often more, will go for the one shipping rate. I automatically give refunds when lots are combined.
