My favorite drawing pens are Faber Castell Pitt Artist Pens, shown right as the top three pens with their caps off. I love them because they are wonderfully waterproofed India ink, and work best of all the pens on shellacked paper, which I am loving in my journal. Their range is excellent, shown above, and can be subtle, bright, or layered, even on shellac! I normally work in Dark Sepia, Sanguine or black to sketch, in sizes XS, S, F, and brush. I have two complaints: They only make the white pen in the ultra fat size, and the colors of their tops and cases are deceiving and inaccurate. I have a coral color that looks like a dark red cap, and the red looks pale. Oops! It can lead to mistakes so I must be very careful.
For watercolor pens, I love the Tombow Dual Brush Pen (the orange double tipped pen bottom right with both caps off); I used them in my early years as an architect, and they are wonderful, well-priced, last long, and the tips hold up to a lot of work. Their colors are great and the caps are much closer to the real color! I like them best in a sketch journal, fooling around, shown below. they do not work on shellac.
Currently I am starting to play with the Cocoiro Lettering Pen. One general problem I have with the Pitt and Tombow is the waste — lots of plastic going into landfills. With the Cocoiro you keep the outer pen, and just replace the insides in whatever color and brush type you want; I like less waste in the landfill. I bought four pens, brush black, black hard-tip, sepia hard-tip, and blue-black hard-tip. The prices are good!
One problem with the design is that the caps do not stay on tight. SO, I think they always need to be in a small plastic bag when traveling, or caps will fly off and my purse will be ink-stained. Also, I wish they were India ink or waterproof ink, but watercolor artists like them because they will wash and the color will move. I tried using my waterbrush on them and the ink immediately moved. A new toy for me to get used to as I move into watercolors!
Cocoiro pens on a card made for my husband, where I used Neocolor II crayons and a waterbrush to move the color where I wanted it. He could not tell these guys were owls, but lots of owls have ears. He liked it anyway!
