In preparation for my Holidays in Ink challenge, I've got my eyes open for supplies that might be interesting to work with. That's not to say that I don't have PLENTY right here in the studio, but when I saw this 48-color set of Arteza Real Brush Pens on Amazon Prime Day, my willpower abandoned me! I decided to dive in and give them a test drive, since I love working with ink and brush pens. I did a few sketches and tests with them, along with several comparisons with other non-waterproof inks and brush pens that I'm already using.
