These sheets of “paper” made from limestone and resin. They lay flat, resist tearing and are waterproof. They’re also heavy, and have to ship by themselves, so we’ll calculate the exact cost to ship the package to save you as much as we can. Suitable for watercolor, oil and acrylic paints, pastels, mixed media, and pencils. These sheets are 14 pt = 0.014 in = 0.356 mm thick.
