Thank you for viewing. This is a refill for mizutama's Furukawa Shiko fufufu notebook. M5 square size. (Regular price of one item: 451 yen) Set of 6. All items are new and unopened. I purchased these but haven't had many opportunities to use them, so I've been storing them. This is a private, individual sale. They have been stored at a private residence. Please understand the above before purchasing.
