Review on ✒️ PILOT Parallel Mixable Color Ink Refills: 12 Colors, 12-Pack (77312) - Perfect for Calligraphy Pens! by Mohan Joseph

I bought these to decide what colors I like best for my Pilot Metro short nib. The black ink that came with my pen was great, as was the Monteverde ink I tried, but this ink isn't good. Even on the Rhodia paper, the purple line showed through. It might be better to work with a finer pen or lighter colors but I have what I have and don't really care for lighter colors as I use this pen for journaling not drawing. flows well. Maybe half the time they just don't work moving down even if the ink is already italicized. I will check my Noodler ink as soon as it arrives to make sure the problem is with the ink and not my pen, but everything was fine prior to these cartridges. Ymmv but if you are a writer and not a calligrapher I would be wary of them.
