This is a folding fan for the tea ceremony. It is about 15 centimeters long. A waka poem (by Rikyu?) is designed on it. I purchased it 20-30 years ago for sencha (Japanese tea) practice, but I have only used it a few times. There is no box. Would you like it for practice? For those who understand that this is a long-term storage item, thank you. Thank you for looking.
