Vintage Japan Ceramic Glaze Tea Cups Set of 4 MCM Retro Green Orange White READ

Vintage Japan Ceramic Glaze Tea Cups Set of 4 MCM Retro Green Orange White READ Good preowned condition. One of the cups has a surface crack inside and a small crack on the outside. Hard to see but I tried to capture in the last two pictures. Does not appear to go all the way through the cup. Made in Japan etched on bottom of cups. See pictures for details and measurements. Shipped with care.
