Decorate and insulate with these dark, chunky cork wall/ceiling tiles. These tiles can also be used as a tack board. The multi-functional cork tiles are naturally dark (nearly black) in color. Note: They may have a slightly burnt smell from the production process. This normally dissipates over time. Excellent acoustic and insulative properties. Dimensions per tile: 12" x 12" x 3/8" thick. Sold per pack of 4 tiles.
