The pins of KOH-I-NOOR are very well in hand although they are ground round. What I noticed especial positive, that is the mines are slightly thicker than the meissten pins. I would have found it a bit nicer if the pins were completely outside the paint and not only at the bottom, so it's not so easy to distinguish the colors for me as for the fully painted, because all my crayons are devices provided in this, so that the whole thing just looks neater. But this is also the only point of criticism. The pins are very well pigmented and are not too hard resulting in a high and beautiful opacity brings. For the price absolutely recommendable.
