People always ask what my favorite pens are. I've done several posts on my favorite pens (there's a big extensive list of all of my favorite pens here.) Above is a photo of my absolute, most basic, necessary set of pens. There are my "don't leave home without them" pens:
Rapidosketch .35 (not to be confused with rapidograph which I've found too scratchy for the many layers that we often work on.) I fill it with permanent, waterproof black ink (the own should come with its own bottle if ink.) This is my favorite pen. Be very careful and write normal, taking care not to press hard on the tip (the pen can be fragile. If the tip gets broken, you might as well toss the whole pen as you can buy a replacement tip but it costs as much as the pen. I don't clean mine after every use. Instead, I make sure to store it flat and if I haven't used it every 2 weeks or so, I make sure to use it. Another quick tip, you only need to fill it less than halfway. Keep an old rag around to wipe off excess ink. Turn any parts gently until the stop. Don't twist anything too hard.)
Sakura Gloss Pink Glaze Pen (I love all products that Sakura makes, especially the Glaze and Shuffle pens but this one is my absolute favorite color!)
My little cigarette case (that's what they market them at the $.99 in Japantown, San Francisco to be) full of Pilot Latte and Sweets (it looks like as of this writing 12/8/2011 that Jetpens is out of the sets of the Sweets. They have some individually.) The difference between the Lattes and the Sweets are the colors. I. Love. These. Pens. The tips are tiny. I love coloring in with them. They last forever. (JetPens is the best place for these pens and a lot of other fun pens. Jetpens is a small company and they offer awesome service. I've been ordering from them for a long time.)
Update on 12/9/2011 on the Sweets Pens. The Sweets have been discontinued but the Lattes are still available. More here.
What are your favorites and why?
