Acid free, natural white 93 lb. (150 gsm) sheet has an excellent surface structure for a wide use of mixed media, an excellent addition to any artist's sketchbook repertoire. Distinctly two sided with a cold-pressed pronounced texture for dry media on top and a smoother hot-pressed surface for pen and ink, and mixed media on the bottom. The double wire binding creates a flat surface, allowing the artist to draw across the page. The sturdy black chipboard cover can be personalized with acrylics to make your journal as distinctive as your artwork! Extra heavyweight 100% recycled chipboard front and back cover make these books perfect for field work. Micro-perforated to true size for easy sheet removal. Proudly made in the USA.
