Review on Watercolor ParKoo Flexible Painting Calligraphy by Linda Diaz

These really are brush pens. Not like brush tip markers, but a real nylon brush tip (individual individual hairs). It's like painting with a small watercolor brush. They apply pigment well and the colors match the caps very well. A refillable water pen is included so you can mix colors, but I don't think you'll get bright, desaturated colors with it. I thought it was more like brush markers and I may not be the best judge for myself, I'm not very good with watercolor paints. But if you're a watercolor artist looking for a portable solution, it might be worth trying, especially for the price (at least for today's price, less than $15).
