A pad containing Sennelier D340 paper, specially designed for oil paint, oil sticks, and acrylics. This hard and rigid bright white paper resists penetration of oily art media, and is stiff enough to aid in preventing paint films from cracking. Prime sheet before using with oil paints. Machine-made, two-sided (rough/cold pressed), heavyweight acid-free paper that is top side glue bound. Also excellent for drawing, water media, pen and ink.
