Dress up your home with these elegant window boxes. With clean lines and raised panel detailing, they have the look of fine woodworking. But unlike wooden window boxes these are virtually maintenance free because they're made from high quality polyethylene — there's no need for annual painting or staining. With the best UV protection in the industry, these window boxes have a 15-year guarantee against fading. They're self-watering, too. Just fill the reservoirs and the planters deliver water to plants as they need it, for healthy, lush flowers and foliage. High quality, UV-protected polyethylene.
