Our notebooks are printed with faint lines only on the front side. We have intentionally left the back side blank. We did this so that you can use the back freely like a plain sheet of paper, guided by the subtle transparency of the lines from the front.

We hope you enjoy the pleasure of writing on a clean, white page and the joy of using it in your own unique way.

Even without explicit guides, the lines on the front act as a gentle assistant, making this paper kind and easy to use at your own pace—whether you are writing straight or drawing pictures.

Furthermore, we use water-based ink to achieve a soft, crayon-like line. Because of this, the ink is quite delicate and prone to bleeding if it gets wet. Please take a little extra care to keep it away from rain and water droplets while you use it.

It is highly compatible with ballpoint pens, and in particular:
• Mitsubishi Jetstream
• Pilot Juice Up 0.4
• Zebra Sarasa
provide an excellent writing experience, allowing you to write smoothly and effortlessly.
Furthermore, the paper used is high-quality paper found in Japanese books, so you can use it with confidence for your daily records and notes.

A lifelong companion

The Birth Book Leather binder is like a "lifelong companion" that stays by your side for years to come.
The more you use the leather, the more it conforms to your hand, slowly developing a unique character that is yours alone.

Since it uses a loose-leaf system, you can use it indefinitely by swapping out the contents—whether as a planner, a diary, or a work notebook—to suit your needs.

It is the perfect choice not only for yourself but also as a gift when you want to give something that will last.

Furthermore, its B5 size makes it a popular choice for gifts such as school enrollment or job celebration presents.
Being a standard B5 size, it also offers the convenience of being compatible with loose-leaf paper from any manufacturer (such as Kokuyo, Maruman, Laconique, etc.).
