I wanted to test out a new Bic 4 Color I had purchased, but couldn't think of anything to draw. Well, I had already written with it a fair deal, but that's not the same as drawing.
Anyways, I ended up drawing my sonas. Not characters that tend to interact, but it allowed me to use all 4 colors of the new, smoother, Bic.
My verdict: better than the original for writing, worse for drawing if you're after gradients

I would like to do another piece going over a cheaper vs. expensive fountain pen to once again talk about how you don't need the fanciest thing or a 14K gold nib to have a good pen.
