This is a set of 12 wall panels. They measure 19.7 in by 19.7 in and are in Walnut color. They are made of plastic and formed to appear like they are wooden slats. This makes a convenient wall panel that is lightweight, easy to install, and also easy to clean. This set of wall panels could be the beginning of many great projects. They could also be ideal to cover a troubled spot on your walls, or even on a piece of furniture such as a freestanding buffet table or bar. I like that they are lightweight, they are easy to glue, screw and cut! I am very happy to have this set of wall panels to work with!
