Kuretake No. 6 Double Sided Brush Pen - Soft - Gray & Black Ink

My favorite Kuretake Brush marker. A perfect sketching marker. I LOVE the double shades for depth. The length is a generous 7.5" which I find perfect when holding my brushes in the upright position, but is no problem for me in the pencil position either. Both inks are water soluble, great flow (you can get both dry brush and wet brush techniques out of it), the grey head is slightly smaller/narrower than the black head. A very versatile pen.

I bought this pen to try a Kuretake felt tip. I loved the idea of the dual tip grey/black.
This pen really surprised me. It is very natural to control the tip and get the line you want,
love that you can get a nice thin or beautiful thick line. The ink that comes out is amazing, it soaks into the paper beautifully and does not bleed or feather. My only complaint and it is very minor, is that it is a bit longer then I would like but it is not a problem.

I think this is a wonderful brush pen. The tips are similar to those of copic markers, which are soft but still easy to control. I am in love with the dual black and gray pens, because you can use them for shadows and to create tonal variation within the drawing.
The pen is pretty too :). I like the black with the silver writing, and it has a good length if you want to use it in a more traditional fude brush manner.
