Nine (9) vintage white plastic buttons of unknown manufacture. 5/8" (16mm) chunky circle with concave square center and angled curved sides. On each side is a recessed half-moon shape with a series of cut stripes. The backs are concave with a thin flat rim and raised pad in the center. Two-hole sew-through. Being plastic, these should be washable. Good condition with a little dirt in the crevices.
