"値段も少し高いけど、頑張って書く時にはコスパが良いと思います。私は油性、ゲル、万年筆などいろんなペンを使いますが、頭が良くなった気がします気のせいですけど"

Lovely to write on with a fountain pen. Expensive, but really nice.

This has become my new working notebook. Pages are thick enough for fountain pen ink, layout is versatile for notes, journals, or other content. Size options are perfect for all users. This is just a quality beautiful notebook that is perfect for everyday use and great value for the cost. I buy five at a time to keep on hand.Anonymous

I typically get the Maruman basic notebooks in dot grid to take notes at university. However, they were out of stock and I needed a new one, so I got one of these, the slightly nicer stuff. And it is slightly nicer. The paper is heavier, has less show-through. Perhaps a touch smoother as well. I'm not a big fan of the header block at the top of every page, though; I think it wastes space. I would recommend either for fountain pen users.Anonymous
