I’m going to ink this up right now. Do you love R&K’s Helianthus?
I find Violette Pensee to have a little bit of a milkiness to the color. I have no idea what makes that happen. The ink performs well and I do like the color – check out my original review of it right here.
Hofvijver Grijs is a nice middle-of-the-road gray (unless you prefer that it be grey) ink from PW Akkerman.
If you’ve been searching for a US source for Akkerman inks and their iconic bottles, check out Vanness Pen Shop. I’ve only ordered from here once, but had a good experience.
I looooove the way Diamine Amber swabs. The color is pretty amazing and it looks like it has some potential for shading.
As part of a mega-review, I looked at it in detail here and didn’t love it. Reviews on Goulet Pens say that the ink is great, but not for very fine nibs – that may have been my issue and I should give it another go sometime.
What is your experience with Diamine Amber?
