New Notebook (新しいノート)

I bought a jacket for my notebook as shown in the picture. It is called "SYSTEMIC" made by KOKUYO. It is for A5-size notebook. I had used B5-size notebooks so far, but I changed the size. It is a small challenge for me. The jacket is useful because it has pockets for stationaries, bookmarks, and a book belt. In addition, the jacket can be put two notebooks. Above all, I was satisfied with the design.
