I had a pleasant surprise yesterday when my order of Molotow “One 4 All” Paint Markers arrived in the mail. I should add “finally,” since I ordered them online from a store in London, Jackson’s, taking 3 weeks to get here, but they had the best prices.
The pens come in several colors, different tip widths, and refillable bottles. I got a white and black 1mm size, and a large black refill bottle for $25. The tips are hard, but you can get some line variation by pressing down, which increases the flow of paint. With a light touch the lines are fairly thin. Their black paint is quite dark, but the white is slightly transparent, as you can see in the image above with the white drawn on a scrap piece of printed paper. I drew the white over the black marks after it had dried for a whole day, and pressure caused the marks to smear a little. When I scribbled over an area of black the paint turned grey. Although the paint dries to touch very fast, the binder is not strong, causing the blending.
They sell empty pens that you can load with paint or inks. The paint needs to be rather thin to flow out the tip properly, such as in their refills. I’d like to try different brands of similar paint, like Golden’s High Flow. You can thin the acrylic paints with water if you like to add more transparency, and mix you own colors.
