The Canson 1557 Sketch Pad - A3 features a pure, extra-white surface named after the historic year of Canson's founding to honor its legacy of exceptional paper making. Its 50 sheets of lightweight 120gsm paper provide a delicate, double-faced texture that offers a slight grain on one side and a smoother grain on the reverse. This acid-free, highly erasable pad is a favorite among artists and designers because it allows graphite, colored pencils, and charcoal to adhere perfectly while ensuring colors remain bright and clean.
