🖋️ I have so many pens with orange ink in them (I have a problem), I decided to not go matchy matchy with the heat.

I have had Iroshizuku Tsutsuji for a couple years, but wanted a more hot pink. 431 is my first Ink Studio ink, and in my limited writing, it writes great and pairs well with this ECO.
