Thank you for viewing. Two one-go masu (square wooden sake cups) Outer dimensions: 8.5 x 8.5 x 5 cm Inner dimensions: 6.5 x 6.5 x 4 cm These are commemorative items from ANA (All Nippon Airways) flights. There are several stains due to long-term storage at home. I don't know the type of wood. It's difficult to see in the images, but there are round marks on the inside bottom. Please understand this before purchasing.
