Cansons 1557 Cartridge drawing pad offers a bright white paper that is designed to accentuate contrast and allows colours to really stand out. Both surface and internally sized, 1557® paper offers a remarkable resistance to repeated erasing without degradation. Hiding beneath its apparant simplicity, 1557® is a rather sophisticated paper. The grain is neither too smooth nor too prominent, providing a subtle surface perfect for sketching, drawing and other dry techniques. This paper is ideal for precise technical drawings with graphite or hard leads. 1557® paper retains pigments well and allows unlimited shading and gradients.
