Thank you for viewing. This is a refill for mizutama's Furukawa Shiko fufufu planner. It is a set of 6, with 30 sheets each. M6 size. The retail price was 473 yen each. All items are new and unopened. I purchased these but haven't had a chance to use them, so I've been storing them. This is a private, individual sale. They have been stored in a private home. Please understand the above before purchasing.
