Sirio Ultra Black is a premium quality uncoated paper and cardstock manufactured in Italy by the mill Fedrigoni. It is recognized for being the deepest, most intense "blackest black" paper in the world! The paper is solid core so the color goes all the way through - there are no white edges if you cut the sheet. The surface is Satin Smooth and produced with FSC certified fiber, acid-free, and pH neutral to insure longevity and archival quality.
