Spectrum Noir Illustrator Pens 3-Pack
These dual-tip pens provide a thin marker point and a fat brush tip for drawing thin and thick lines. The ink dries quickly and they feel like Sharpie-style permanent markers. Three-pack includes black, blue, and red ink.
Bizarre hexagonal styling looks cool and prevents them from rolling off the desk, but they feel somewhat odd (not bad though, they take time to get used to.)
Good for all purpose drawing, inking, sketching, and coloring. The dual tip design is nice for drawings where you want a fine point for detail and a brush for outside lines in a pinch.
