The Hobonichi Techo uses 12 soft colours across the book. The TSUKI no IRO stationery series incorporates these colours into simple designs.

This set of six Uniball One pens features vibrant, bold ink colours selected in colours that go well with the printing colours used for each of the twelve months in the Hobonichi Techo.

The twelve colours are divided into two sets of six pens—one for January through June, and the other for July through December—each housed in an original case.

The Jan–June Set includes:
January – Mandarin Orange
February – Brown Black
March – Plum Purple
April – Poppy Red
May – Avocado Green
June – Green Black

The July–December Set includes:
July – Nemophila Blue
August – Blue Black
September – Cappuccino Brown
October – Violet
November – Emerald
December – Red

Each pen features the original TSUKI no IRO logo and HOBONICHI TECHO printed in the matching monthly color on the barrel.

The pen cases take inspiration from the colors of February and July, with one in brown and the other in blue. A pocket on the back offers extra storage, perfect not only for pens but also for sticky notes, stickers, and other small stationery items.

You can use the pens to go with the printed colors of the techo pages, or add seasonal color accents to pages that aren’t printed in the monthly colors, such as the monthly calendar or Weeks pages.




Other stationery items are also available in the TSUKI no IRO series. Enjoy the world of all twelve colours!
