Derwent's best water-soluble pencil ever, the Derwent Inktense Pencils range contains 71 pure, vibrant colours plus a non-soluble outliner.
Derwent Inktense Pencils can be used dry but when mixed with water the colour turns into vibrant ink. Once dried, the colour is fixed and can be worked over the top of it. Great for using on fabric such as silk and cotton. (You must make sure that all the pigment has been dissolved in the water to make it permanent. Any dry pigment will be washed out if further water is applied.)
