Kuretake pens.

Kuretake pens over my drawing, made with this pens. Here is few kinds I used, Twin, H20, Brushables and Clean Color. What is interesting about Brushables color is slightly  different on both sides, which gives you so many options to experiment. I didn't include Kuretake 13, Letter pen and couple of other brush pens I have. I didn't use it on this drawing.
