It works fine with every kind of drawing implement I have tried: * pencil * charcoal * ball-point (needs additional weight on the pen) * roller-ball * felt-tip * fibre-tip It draws so slowly that there's no issue about waiting for the ink to dry. But what I like best is soft pencil on slightly textured paper. Daniele
