Cheap Ballpoint pen Brush

I made this single brush preset that I use for casual sketching. This supposed to imitate the look and feel of cheap ballpoint pen that I commonly use. This brush uses multiply blending. Using this brush on a transparent layer may result in a thin white outline. Use in a flat layer or in layer with ‘darken’ blending to remove the outline. [Testpen] [testpen2]
