PaintON® is an extra heavyweight art paper designed to support almost any medium. The sturdy 115 lb (250 gsm) paper is perfect for playing with pen & ink, gouache, pastels, acrylics, collage, and more! PaintON® sheets are double-sized to resist buckling, so you don't have to hold back. You can paint as many layers as you want because the paper has exceptional wet strength. A very light grain surface makes the paper ideal for precise drawing. The surface can even withstand repeated erasing without pilling. Colored paper pads are deep-dyed, so there are no annoying white cores to uncover.
