This is a set of 3 vintage plastic buttons by Famous Buttons. They are a smooth thin larger plastic button with a fibre optic look that shimmers what I would say is copper brown. They are 23mm or 7/8" wide and 1/8" or 2mm deep. They are shank type and held together with a piece of wire in the back. My inlaws had a general store until 1965 so I know these are at least 55 years old. I will happily combine purchases paid together within a 7 day period.
