These wall tiles are made with porcelain and glaze. Each varies in color, see each variation listed in images. Each wall tile comes with a hole in the back for a thick nail or screw so it can hang on the wall. Use an area where there is a stud ir a heavy wall anchor for the best possible outcome. These are hollowed out, but the glaze makes them heavy. Can also be put on a table stand to be used for a table accent. Grouping them can really make a modern wall accent.
