PS frames very easy to lift, transport, and hang, especially for large poster frames or oversized pieces. Unlike natural wood, polystyrene is not prone to rot, mold, or warping due to changes in humidity, making it an excellent choice for bathrooms, basements, or other damp environments. The material can be intricately molded and covered with finishes to convincingly mimic the look of real wood grain, antique gold leaf, or sleek metal, offering high aesthetic value without the high cost.
