Arches 300 lb Block 9" x 12"
The power of 300 lb. Arches paper meets the portability of a watercolor block (glued on all four sides.) The cold-pressed sheets are 100% cotton, acid-free and buffered with an anti-microbial agent to help resist mildew. Each block contains ten sheets of natural white paper, and is protected by a black protective sheet under its cover.
