The Oil Pastel Paper Pad is designed exclusively for oil pastels, featuring advanced formulation that prevents oil seepage and bleeding through the paper. Each pad comprises 12 sheets of acid-free paper, boasting a weight of 160 lb. (340 gsm). These sheets are thoughtfully interleaved with glassine layers, adding a protective element to your artwork. The pads are conveniently available in four dimensions: 16x24cm, 24x32cm, 30x40cm, and 40x60cm. Bound with a spiral along the narrow edge, this setup ensures ease of use and practicality for artists working with oil pastels.
