This Derwent Academy Heavyweight Marker Paper Pad is the perfect choice for aspiring artists and hobbyists. The paper's ultra-smooth texture is designed for drawing with permanent and water-based markers and pens. Its heavyweight 50 lb. sheets ensure ink won't feather or bleed through pages. The paper is white and acid-free to keep artwork looking its best and won't yellow or degrade over time. The pad's topbound sheets easily flip back when it's time to start a new drawing. Pad contains 40 sheets and each sheet measures 9" x 12".
