The Hobonichi Techo Original and Cousin use a 12-color system, with a distinct color assigned to each month's grid. This curated selection of Uni-ball One gel pens was chosen to closely complement those monthly page colors, making them an easy and thoughtful pairing for Hobonichi users.

These shades correspond to the same color lineup featured in Hobonichi’s Tsuki no Iro Uni-ball One sets, but are offered here without the Tsuki no Iro branding or storage case. It’s a practical way to enjoy the color coordination without committing to a boxed set.

Colors are available in grouped in sets covering January - June (Set 1) and July - December (Set 2).

Monthly closest color match:

Set 1
January – Mandarin Orange
February – Brown Black
March – Plum Purple
April – Poppy Red
May – Avocado Green
June – Green Black

Set 2
July – Nemophila Blue
August – Blue Black
September – Cappuccino Brown
October – Violet
November – Emerald
December – Red

Please note: that while these pens are selected to harmonize with the Hobonichi monthly colors, the ink shades may not be an exact match to the printed pages.
