Making prestigious art papers since 1492, Arches has been the paper of choice for artists. This archival paper is mold-made with 100% cotton fibers, has a natural white luster and stands the test of time. A process exclusive to Arches, gelatin sizing to the core gives each sheet astounding absorbency, as the pH-neutral, gelatin-sized internal and external fibers hold pigment in place without over-saturation. Each pad has a thick, pulp-dyed backboard for extra rigidity and stability. Easily correct liquid media mistakes repeatedly and with minimal warping to the textured paper. Each pristine sheet has been securely fastened with a strong spiral binding that aids in shape-retention. This exquisite, thick cotton paper functions well with all wet techniques as the cotton fibers adapt to whatever medium you use to craft your work. Arches cold press watercolor paper contains no optical brightening agents. This package contains a 10x6 inch watercolor journal. 140lb, 15 Sheets.
