I bought these cartridges to send out as samples or for swapping inks with friends; it’s a lot easier to send these in the mail and avoid ink spillage.
I was expecting this colour to be more red-leaning, but it is more of a neutral blue-black, or perhaps even grey-leaning, depending on the paper. I like it best on white paper.
It does not lean red like my preferred CdA Magnetic Blue, Pilot Iroshizuku Shin Kai or Diamine Midnight. It’s similar to Aurora Blue-Black. The Platinum Blue-Black that came with the Preppy is a lot bluer than this Kaweco ink, and the Diamine Chopin from the Music Collection is greyer.
With my pen and paper combos, the ink dries to a flat or matte finish. It’s not a very saturated ink; it does dry quickly. Its flow is average, shading is minimal, and I prefer using it in my Sailor 1911L 21 kt H-B because I can achieve a dark, contained, crisp line. I’ve observed no feathering, no bleedthrough, little ghosting, no hard starts, skipping or nib dry-out. It cleans out easily from converters.
I’m glad I tried this ink and got to compare it to other inks in the same colour category. It’s a solid performer, but I just prefer other blue-blacks.
