Ten (10) vintage Streamline matte brown plastic buttons with a wood grain appearance. Almost square rectangles with a curved top on a slightly larger base. The color is lighter in the center and gets gradually darker as it nears the rim. Approximately 5/8" (16mm) x 19/32" (15mm). The backs are flat with a slightly raised circular pad in the center. Four-hole, sew-through attached to the cards with staples. There are no care instructions on the cards but these should be washable. Very good condition.
