This is for 20 sheets of Itajime dyed Japanese paper. We currently have enough stock for 2 more sets, so if you would like to purchase more, please feel free to comment and we will adjust the product page for the desired quantity. We are unable to offer discounts as we have already sold multiple items at this price. Measurements are approximate: 31cm x 23cm. These items were found while organizing my parents' home and I do not have detailed information about them. The original packaging was deteriorated and dirty, so they have been placed in new bags. These are stored at home, so we would appreciate it if those who understand used items would consider purchasing them.
