Recycled polystyrene rods provide rigid armatures for sculpture, floral arrangements, and dimensional installations without adding weight. These extruded foam cylinders maintain structural integrity under repeated manipulation, pins, wires, and skewers sink cleanly without crumbling or splitting. White surface accepts paint, paper, fabric, and adhesives directly, letting you build up texture and color through successive layers. Lightweight construction makes large-scale work manageable; you can construct frameworks and vertical elements that would be unwieldy in wood or metal.

The closed-cell foam resists moisture and won't deteriorate when exposed to standard craft adhesives or water-based finishes. Cut rods to length with basic tools, carve surface details, or leave smooth for clean geometric forms. Floral designers use them as structural cores for large arrangements, while sculptors appreciate how they eliminate weight concerns when building armatures for mixed-media work. Available in multiple diameters to match project scale, slender rods for delicate structures, thicker ones for substantial installations that need internal support.
