☆One-of-a-kind, Brand New, Unused☆ ☆M5 System Notebook Square Back Notebook☆ ☆ASHFORD Notebook M5 Size☆ ☆Color: Green☆ This is a one-of-a-kind item, so it will likely be difficult to obtain in the future. Therefore, I am listing it as a rare and valuable item. Please understand. I enjoy collecting stationery, writing instruments, high-end writing instruments, and leather goods, and this item seems to be a one-of-a-kind notebook sold at an Ashford event, which I received as a gift. I also use other notebooks such as Il Bisonte, Ashford Bible size, M6 size Coachman, Filofax HB, Knox, Davinci, Raymay Fujii Roroma Classic A5, etc., and I don't have much opportunity to use this one, so I am selling it. Size: Height: Approximately 11.8cm Width: Approximately 7.5cm Depth: Approximately 1.6cm I am unsure of the ring diameter. Since I am measuring it myself, there may be some errors in the size. Please understand and purchase accordingly. Although it is a new, unused item, it has been stored and inspected by an amateur. Since you are purchasing a one-of-a-kind item, there is no box. If you are concerned about this or are looking for a perfect item, please refrain from purchasing. Notebook Size: Other Sizes Color: Green
