Well-priced for students and beginners, this machine-made, acid-free watercolour paper is made of a valuable mixture of lignin-free cellulose and 25% cotton, making it excellent for watercolor, gouache, acrylic, ink, charcoal and greeting card design. Its 140 lbs. cold-press surface feels like 100% cotton rag. It is sized internally and externally, allowing for optimal absorbance.
