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 3/8'' MDF 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. The uncradled panels feature slots on the back for easy hanging. Brand: Ampersand
