If you like the look of long bars and beveled edges, then Bob's Panel Premier Window Box with Faux Brackets just might be the perfect addition for your home. This product is made from durable Composite PVC, which looks and feels just like wood without all the hassle. These PVC window boxes will never rot, grow mildew, or attract insects, no matter how humid it is outside. White windows are an excellent complement for home exteriors decorated with cream, medium-gray, and cold colors. This window box comes with three pillars underneath - two on each side, and one in the middle.
