This is a set of 5 Kokuyo notebooks. I bought them because I thought the design was cute, but I haven't had a chance to use them, so I'm selling them. They are new and unused. A: Standard ruled × 4 B: Standard ruled × 1 One of the A-ruled notebooks has a graph ruled design, which is very convenient for drawing diagrams and tables. The dots are light, so you can of course use it as a regular notebook. It helps you balance your writing and makes it easier to write neatly. *Please refrain from purchasing if you are concerned about storage by a private individual.
