Natural wood finished masu, traditional design. - Material: Wood - Type: Masu (measuring box) - Dimensions: Square shape - Design: Natural wood finish with engraved symbol Thank you for viewing. I don't see 1-sho masu (a specific size of masu) very often these days. It can be used as a decoration for the bean-throwing ceremony, etc. The wood on the bottom is slightly peeled, but there is no problem with use.
