I haven't spent enough time using them to properly compare them to my Prismacolors but they lay down smoothly and richly. I bought four of the maximum lightfast pencils (three stars) during the buy 2 get 2 sale: Dark Indigo, Cobalt Green, Pompeian Red, and Beige Red. I wanted to try them out first and if I liked them, not have duplicates within one of the smaller sets. I've enjoyed them so far! :)
I doodled this cute little rat. She's outlined in Indigo which was also used in the darker hearts and on her nose and whiskers. Her fur is Pompeian Red and her paws, tail, and inner ears are all Beige Red. Her irises and the gradient in the heart is Cobalt Green. (The two reddish hearts are other products and the highlights were all added/enhanced with Yono White or Montana White Acrylic Markers.)
