Sketch Block DN-F6 F6 (410 x 320) Deneb, the highest quality watercolor paper, 18 sheets Retail price: 2970 yen Set of 3 This paper has a medium to rough texture with a firm, uneven surface. The strong fibers firmly hold the surface, so it can withstand scrubbing with hog bristle brushes or wiping with sponges or cloths. Although the absorption is slow, the fibers hold the pigments well, resulting in good color development with no repelling effect. The materials do not contain fluorescent agents, and the pulp mixed with cotton is non-wood. This paper achieves high quality while being environmentally friendly. Because it does not use fluorescent agents, the paper has a gentle white color. These are new, unopened items that have been stored at home. Please consider this when purchasing.
