A set of two sake cups: one blue Bizen ware and one Bizen ware, from the early Showa era. The kilns are different. The artist is unknown as there is no box. They have a sense of age. As they are antique items, there are kiln cracks and sesame seed glaze (kase goma), so please take a close look at the photos before purchasing. Blue Bizen: Diameter 5.5cm, Height 4cm Bizen: Diameter 5.6cm, Height 5.7cm
