Promarker markers were originally designed for drawing cartoons and manga, but thanks to the excellent marker mark, they are also great for coloring drawings and stamp designs. The mark of Promarker markers is even and the coloring marks seem to melt together, so the end result is "streakless" and neat. The markers have two different tips: a narrow drawing tip for precise work and a wider, chisel coloring tip. Additional effects can be made on top of the dry marker surface either with Promarker markers of different shades or with watercolor wood colors, fountain pens, paint markers or any color with enough pigment to cover the Promarker marker's mark. Promarker markers are non-toxic and alcohol-thinned. The markers are not acid-free, so it is not recommended to use them with photos. Markers should be stored horizontally, with the cap carefully closed. In the horizontal plane, the dye inside the marker is distributed evenly on both ends, and thus both tips are immediately ready for use. When stored correctly and used on the right paper, the colors last a long time, and the tips of the markers do not "fray".
