Vintage pillbox, brass and bone box - 1970s

Pill box, small vintage brass collector's box with inlay on the lid of a rosette which I think is made of bone (or shell?) on the lid. The heart of the flower is set with a brass circle. The last photo next to a pencil shows the scale of the box. Excellent condition of the piece which most probably dates from the 1970s: no shock, no missing. Diameter: 4 cm. Height with lid: 2 cm. Depth without lid: 1.5 cm. Weight: 30g.
