One pen that does two jobs: a flexible brush tip for broad washes and a fine fibre tip for detail lines. Staedtler Marsgraphic Duo works with or without water, so you can sketch dry or go full watercolour without swapping tools. Brush tip ranges from about 1.0 to 6.0mm; the fine tip sits around 0.5 to 0.8mm. A box of 18 means your art room, design studio, or classroom doesn't run dry halfway through a project
