Vtg Japanese Hand-Painted Porcelain Mini Bowls

Vintage ornate, hand-painted miniature porcelain bowls, possibly sake cups. Set of 4, in original box. Previously owned but in good condition. One cup has a chip near the rim, and the box is in pretty worn condition (look closely at photos). The main color is gold, with hand-painted scenes of flowers, geisha, butterflies, and birds. Each measures 1” in height and 9” in circumference. If you have any questions, please ask. :)
