Three (3) vintage plastic coat buttons of unknown manufacture. Large 1-5/16" (33mm) circle with shallow dome center surrounded by a deep channel curving up to a thin flat rim. The color is a soft milk-chocolate brown. Straight sides, about 3/16" deep, with flat backs and extended looped silver metal shank; these have the original cotter pins from when they were attached to their card. I have no manufacturer information so no care instructions but these should be washable. Very good condition.
