Size: Closed Width: 21 cm Height: 16 cm Please note that these measurements are approximate due to being taken by a non-professional. There are pockets on both sides when opened. The right side has three additional pockets. Please refrain from purchasing if you are concerned about minor details, as this is a used item. There is some staining inside the pockets, as I used to keep a planner and cards in them. See photo 7. Thank you for looking.
