Ergosoft is Staedtler's top range of pencils, above Noris. They are a mid price range pencil so not in the league of Polychromos and Prismacolor. They perform well and the features of the stand up case and the barrel shape work well. The range of colours suits me too. There are good pinks, reds, blues and I'd like one more green. Thankfully there aren't too many yellows or greys. For the full review see here – http://goo.gl/dTqb4S
