I have a notebook refill of the moon phase calendar "Michiru". This is a notebook refill to enjoy the phases of the moon and ink. The set includes 12 months of the 2026 calendar and 28 days of 1-day pages where you can write down the phases of the moon and wishes. There are two sizes: M6 and M5. The calendar uses the same soft paper as Michiru, and Michiru's worldview has been redesigned for the notebook. The color that changes every month is also a gentle color just like Michiru's image. (*There is no embossing.) ） On the 1day page, I used "Graphiro" by Kobe School Planning, which pursued the writing characteristics of a fountain pen. It features a clear outline of the letters without bleeding or blurring and a soothing touch of a soggy fountain pen. I painted the shape of the moon of the day and wrote my wishes. It is a page where you can enjoy the fun of writing with a fountain pen. The period from the new moon to the full moon is the period of fullness. It's a good time to make new plans. The full moon to the new moon is a period of waning and is said to be a time of organization and reflection. Make a wish on the new moon or full moon, or draw the moon in the night sky when you suddenly want to start something new. If you try recording it with your favorite ink, you may feel the rhythm of the moon.
