Experience sketching like never before! Molotow s professional-quality Sketcher features a sophisticated ink technology: AQUAPRO ink. With good UV resistance, the ink dries as quickly as alcohol-based inks. AQUAPRO ink does not bleed through paper: fast design sketches can be drawn on thin and conventional copy paper without a bleed-through effect. Thus, artwork and paper lying under a painted sheet will not get dirty, so the sheet can be painted on both sides.
