Wonderful set of 6 pins in varying degrees. I use them exclusively for artistic drawing and am very satisfied. Rich black, fine strokes, dry ratzfatz and smeared nothing. On different paper substrates (watercolor, smooth cards, fine thin paper ...) can always equally well. No blobs or become thicker points on the character lines when short breaks in the strokes. Thumbs up for this product. Hope they have a long life, but if they need to be replaced, then again what this brand.
