Tombow ABT Dual Brush Pen for Art and Comics
I bought a set of Tombows and I found them easy to work with and leave a solid black line. Here is some info from their site:
“2 tips, 96 vivid colours: The fibre pen for maximum creativity. The water-soluble, water-based colours can be mixed together for creating wonderful colour gradients and watercolour effects.” (click here)
The fine tip is for exact or thin lines (obviously), while the other side has a thicker more flexible tip that mimics a brush.
Here are some quick samples I did to test it out. I tried a variety of styles to get a sense of how it feels. Overall, I give it a good rating. I’ll keep this in my toolbox.
