HITOTOKI Square Notebook by KING JIM - Premium Japanese Stationery for Journaling, Note Taking & Office Use

The concept of this notebook is to combine the best features of a diary and a notebook. It has grids like a diary, but the dates are blank. You can use them at your own pace, whether it's the first time in three days or a month, without being tied to dates. It's a notebook that you can use at your own pace.

The book is bound perfectly to open horizontally, making it easy to write anywhere on the page and reread. The pages are also perforated in the middle so that they can be neatly torn off, so if you make a mistake, you can rewrite it.
