Strathmore 400 Series Acrylic Pads are heavyweight and versatile acid-free paper, made with the acrylic artist in mind. The paper has a cream-coloured linen finish. The flipover cover makes it easy to work in the pad, and sheets stay in the pad yet tear out cleanly. 10 sheets per pad. Also well suited for a variety of other painting, drawing, pastel, or charcoal applications where a heavy paper with a toothy surface is desirable.
