These oversized planters are crafted by hand and are composed of highly recycled material. Corten Steel will patina or rust to a beautiful finish over a period of 3 to 9 months depending on your location and climate. The patina/rust acts as a protective barrier, neither penetrating nor compromising the structural integrity of the material. This Corten planter is designed and manufactured in Brooklyn, NY. Each planter is made to order so please allow at least 2 weeks prior to shipping. This item is non-returnable.
