These panels feature an ultra-smooth finished surface that is great for oils, acrylics and mixed media. A warp-resistant, non-flexible alternative to canvas, the panel is made of top quality 1/8" Ampersand True Artist Hardboard with a smooth acrylic coating. The surface allows for fine brushwork and palette knife painting. It is also perfect for mounting papers, prints and canvas. Available uncradled or with a 7/8" or 1-1/2" primed pine cradle.
