This is a popular system planner from Kiiro Works. It arrived in late February. I put refills in it once, but I never used it, and it has been stored on a collection shelf. I am selling it because my collection has grown, and I want to sell it while it's still in good condition! Size: M5 Ring diameter: 15mm, Gold Leather type/color: Sibilla Lisio, Cenere Stitching: Lavender Hook: Gold (with engraving) Shape: Half-moon, HM5xWM6 It's a cute, rounded planner. There are some natural markings and wrinkles in the leather (photos 4 and 5). It originally did not come with a box. It will be wrapped in bubble wrap and shipped via Takkyubin Compact. Due to fees and shipping costs, the price is slightly higher than the purchase price. Thank you for your understanding.
