Bright white paper for all drawing media Our Pen & Ink Book combines technically proficient paper with a sturdy, practical binding. Instead of one floppy back cover, our book includes two heavyweight covers — you can even draw standing up. Instead of the wire binding that gets squished and deformed, we've used an extra-heavy-gauge, solid aluminum coil that travels better and stays in shape. For our Pen & Ink Book, we've selected a German-milled, bright white, pen-friendly paper that holds ink without feathering or bleeding. Use fountain pens, dip pens, brush pens, and all kinds of other drawing media on this highly versatile paper stock. The Pen & Ink Book measures 5.8" x 8.3" and is bound on the short side. Each book has a generous 50 sheets of drawing paper in bright white. Paper weight: 55 lb. / 120 gsm. Cut and assembled in the United States, with interior paper milled in Germany.
