It appears to be a sake cup made from Yakusugi cedar. There are five of them, stored in a box. Are they for drinking sake? They could also be used for snacks, or perhaps to hold beans. I'm not sure what the best use for them is, so please use them according to your own sensibilities. These items were at my parents' house, so I believe they are unused, but I can't be certain. The box has some stains, so I will pack only the cups themselves and ship them in a Takkyubin Compact box. Approximately 5.4cm x 5.4cm x height 3.4cm
