and Pilot Iroshizuku Murasaki-Shikibu inks
Assorted dip pens
At the beginning of every month, five vials of ink samples arrive in my mailbox via the Goulet Pen Company Ink Drop. I don't always have time to test drive all of them right away, but this month I pulled them out and played with a bunch of dip pens to see what the colors looked like and how they washed with a wet brush. Every color was a winner, and I found myself surprised by how much I enjoyed working with the scented inks like the Rose and Hyacinth.
None of these inks are "archival" in terms of being able to hang a sketch on a wall where it would be exposed to sunlight. But they should fare fine inside a sketchbook as long as it's not dipped in water!
