Cobra Oil Color Paper is specially developed for artists who want to paint responsibly and freely anywhere, without solvents for a healthy environment. Paper is easier to take with you and is cheaper than a canvas, so it is also ideal if you want to make multiple sketches. If you would like to paint with oil paint on paper, you need specially prepared paper. A special external glue applied to the paper prevents the oil from soaking through the paper. Acid-free paper. Work on paper is guaranteed to remain in good condition for years. This product is made of material from well-managed, FSC certified forests and other controlled sources.Details:White sheets8.3" x 11.7" (A4)140lb/300gsm10 sheetsAcid freeEnvironmentally friendlyFor use with oil paints
