Ideal for working with India ink, fountain pens and acrylic markers as well as other water-based pens with minimum abrasion. Bound in several layers and thread stitched, the design allows you to work on two pages across the center seam. The attractive design features an anthracite colored cover that is nice to the touch and appears like precious wood.Details:Light gray8.2" x 5.8"55 lb.
