Set of 3 1970s Kiso Hinoki Cypress Wood Sake Egg Cups Small Square Dishes in Box In good, vintage condition. There are some cracks in the wood from age, shown in photos. I’m unsure of their official use, if they are sake cups or egg cups, but they could be used as either. One picture shows them with full scale glass eggs to show scale and purpose. Glass eggs not included purchase. Each cup measures approximately 2.125” w x 2.125” d x 1.25” h The box measures approximately 7” d x 2.625” w x 1.375” h Set and packaging weighs 8 oz.
