Our classicwindow box is truly unique and has tremendous versatility inside or out. Being made from lightweight fiberglass resin, it is also easily moved to different locations, yet by looking at it you would think it is made from stone. Though they look like ancient European and Mediterranean designs in carved stone, our products are made of lightweight weatherproof ResinStone. So authentic, you actually have to lift these planters to convince yourself they"re not stone at all.
