Yes, the fiberstone square planters are cubes. Fiberstone planters are made from a blend of finely crushed stone and reinforced with glass fiber. Our stylish Fiberstone pots come in a variety of sizes and shapes, from small to large. These pots are a perfect option for outdoor use as they will withstand most weather conditions. We do recommend protecting your pot from severe winter conditions. It is best to empty your pots and store them for winter. Moulding Wax is designed for Fiberstone pots, providing a protective layer that enhances their shine and shields them from fading, dust, and harsh weather. Simply apply a small amount with a microfiber cloth or soft rag, rubbing it gently into the surface for a polished, long-lasting finish. To keep your pot looking its best, a complimentary small can of wax is included with every Fiberstone pot purchase. Made in Vietnam
