Our 400 Series Marker paper was developed for fine artists who create finished art using markers. The smooth surfaces allows markers to glide easily, providing easy blending. Colors look vibrant and crisp. The acid free, heavyweight sheet is bleed and feather resistant so artists can apply multiple layers of color. Proudly made in the USA. Media Applications: Alcohol-based markers, water-based markers, solvent-based markers, pen & ink, mechanical pencil.
