A spiral is a space-saving shape, and that is the practical argument for this pair. Each tree reaches 47 in of height on a footprint of only 9.5 in by 9.5 in, so the greenery climbs upward instead of spreading sideways, and two of them can stand where a single bushy plant would not fit. The twist is also simply eye-catching, creating a unique appearance rather than another green blob in a corner. Leaves are durable eco-friendly PE, moulded to imitate real leaves closely enough that the natural, lush appearance holds up at normal viewing distance. They are odorless, fade-resistant, and ultraviolet-resistant, and with UV and water resistance the trees work for both outdoor and indoor use and keep their green all year rather than going pale after one summer. Each pot measures 9.5 in by 9.5 in by 7 in and is finished in gold, filled with cement to guarantee stability so a tall narrow tree does not go over. Inside runs a sturdy metal trunk that keeps the tree upright all the time instead of bowing under its own height. Together the pair weighs 14.5 lbs, light enough to place anywhere and move again later. The trees require no water, soil, fertilizer, sunlight, or pruning, which saves both time and energy, and they are easy to clean and maintain. No assembly is needed. The pair fits a home office, garden, or store, and makes a memorable gift for an opening party or housewarming party.
