Showa Retro Vintage Small sencha tea bowls, set of six. Size: Diameter 6.6 cm, Height 4.3 cm These are cute Showa retro sencha tea bowls. I found them while cleaning up during a renovation. They are new and unused, but have been stored at home for a long time. We look forward to your purchase if you understand this. The original box is included, but it is torn and dirty, so I will send them in a new box.
