Mold-made from 100% rag, this strong and stable paper is acid-free without any optical brighteners. Its buffered surface resists yellowing and maintains archival permanence. Winsor & Newton designed the sizing so that it would absorb color better and assist in color lifting and erasing. Artists consider the natural warm white color an added feature, along with the paper' s random-patterned texture. Four deckle edges and a watermark lend a unique touch to each sheet.
