Incredible! No wood wrapper: pure water-soluble graphite in stick format! Derwent's water-soluble graphite offers you endless applications: you can use it like a pencil, but the real fun starts when you take the paper off! Use the whole stick or break it into pieces to create broad sweeps of color very quickly; then add water and watch the graphite dissolve creating a smooth feel. You can choose from 4 wash intensities, from light to very dark.
