Stabilo's Pen 68 markers are a great all-purpose tool for drawing, illustration, coloring, and crafts. They're a high-quality product for a very affordable price, with a 24-hour cap off time, water-based odorless ink, and excellent color saturation. They're great for coloring, because you can use the top of the tip for small areas and the side for larger strokes. This set comes with 20 colors in a colorful case that converts into a desk stand. Made in Germany.
