Arguably the highest quality markers on the market. Filled with 100% lightfast, water-based india ink, they won't fade under UV light unlike other artist grade markers. Faber Castell PITT pen sets come in a variety of color selections in the small brush size, or with finer pens for technical illustration. Can be used over or under light washes and won't bleed through most papers. The more absorbent the paper, the grainier the effect will be. We recommend Canson XL marker paper and smooth bristol.
