Natural wood finish masu (square wooden cup), traditional design. - Material: Wood - Type: Masu (升) - Dimensions: Square shape - Design: Natural wood finish with engraved symbol Thank you for viewing. I don't see 1-sho masu (a larger 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.
