This is a Rollbahn notebook cover. It can hold two B6-size notebooks, one on each side. It can also hold one thicker notebook, like the Noble Note, as shown in the photo (the notebook in the photo is for reference only and is not included in the sale). I am selling this because I haven't used it since I bought it. I believe the original purchase price was 1,760 yen. - Brand: Rollbahn - Color: Black - Material: Synthetic fiber - Features: With pockets Thank you for looking. Instant purchase is welcome.
