My go to pens are usually Sakura Souffle or Glaze pens. I also love my Micron pens. The points are awesome and gives such detail to things. Use the .05 and the really fine tips, .01. LOVE them!!
When I am journalling I love my Creative Memories colored pens. The CM pens are about a .05 tip. The thin tips are awesome for journalling.
I have several cups of pens on my desk. I love that they are right at my fingertips. I also have some markers, from Creative Memories in thick point that I use sometimes. Watercolor pencils are also on my desk. I do love shading with those when using stamps.
