This is a set of two masu (wooden sake cups) with a branding mark. It includes one 1-go size and one 5-shaku size. (5-shaku is half of 1-go, which is 90cc.) You can use them to measure rice, as a sake cup, or to display small items. I purchased these and stored them without using them. There are some minor scratches from storage, so please take a look at the images.
