The cordless cellular room darkening ivory colored window shade is constructed from textured non-woven polyester fabric that gently blocks natural light from filtering into the room without sacrificing privacy. The cellular fabric also provides a level of insulation to stop cold or hot air at your window. This shade features a unique spring tension device located inside the bottom rail for cordless operation, to operate simply just press the button located on the bottom rail and pull or push. The cordless cellular shade is easy to size and install at home. If you need to cut down the shade to fit a window, you can use the included utility knife and sizing tools; however, we recommend using a heavy duty knife or saw to cut more efficiently. The maximum reduction is 18-inches; 9-inches from either side of the shade. The shade is 100% cordless, so it is safe for children and pets.
