Approximately 36 x 6 cm (measured by hand) I found this while cleaning out my parents' house. I'm not sure about the authenticity, but I think it's genuine because it has a seal. It's an old item, so there is age-related deterioration (please check the photos). ☆ "Hana no Nihoi" So-haku (thin paper) ☆ "Unkai Mangaku Ao" So-i (thick paper, colored paper) #Sohan School #Sohaku #Soi #TeaCeremonyUtensils #Atchi'sTeaCeremonyFlowerArrangementInventory
