Environmentally friendly pens where the pen itself is made of 100% biodegradable material. Of course, you can also purchase refills for the pens. We love sketching and drawing with these pens; the tip is 0.5 mm wide, and the black ink glides smoothly on paper and dries quickly. In this pack, you get four pens, all filled with black ink.
