Persimmon tannin sake bag, stylish handmade fabric NO.21, cylindrical, one side open, length 81cm x 30cm. There are no repairs, but there are short threads sticking out in 7 places. I think it will be no problem if you cut them off. Although they have become less common now, they were dyed with persimmon tannin to enhance the preservation of sake bags, which are necessary in the process of making sake in breweries. The subtle color variations due to the chemical reaction between persimmon tannin and alcohol, as well as the years of use, and the repaired areas, all add to the character of the bag.
