These Planters Pair Traditional Style with Modern Construction Our Napoli Cubes boast an embossed cross-plank and rivet design that evokes farm life or reclaimed cargo crates. These fibreclay planters are made by a patented process using fiberglass resin, crushed terra cotta and other natural materials to produce a durable, lightweight pot. These pots age naturally and attractively over time by absorbing salt, rain and plant fertilizers. Lightweight with the appearance of clay. Available in a variety of sizes and finishes. Ensure proper drainage and protect from hard freeze to avoid cracking.
