In our 2027 TSUKI no IRO lineup, we’re thrilled to introduce a collaboration with Kakimori, a stationery brand beloved by writing enthusiasts worldwide! The collection features fountain pens, rollerball pens, and exclusive ink shades.



If you’re especially intrigued by the inks, we highly recommend the “Mini Ink Bottle Set.” It features 12 distinct shades curated to match the 12 monthly printing colors used inside the hobonichi techo, packaged into two sets of six bottles each (Jan - Jun & Jul - Dec).



As the project leader shared during our Preview Forest livestream, a single mini bottle holds enough ink to refill the Frost pen converter roughly three times! It may look compact, but it provides plenty of writing.

For anyone looking for a quick and easy way to sample these shades, we have the perfect companion item: the “Dip Pen - comoji”! Because its nib is exceptionally fine and slim, it glides smoothly right into the narrow neck of the mini ink bottle.



Since it’s a dip pen, a quick rinse under water lets you jump straight to trying another color. Be sure to check it out if you’re looking to explore the full spectrum of colors!
