These journals deliver high-performing papers and heavy-duty features engineered to meet the intense demands of the artist's creative process. They offer a full range of acid-free paper types and weights and have heavy-duty covers with a wire binding that is thicker and stronger than traditional wire. The binding allows the journal to lie flat and open up 360 degrees. The Mixed-Media Journals contain 34 sheets of vellum-finish 51 lb. paper that is great for wet and dry media including watercolor, acrylic, pen, ink, pencil, crayon, charcoal, marker and collage.
