The “Lucky Seven” water faucet’s spout looks like a growing stalk, and its curved shape resembles the lucky number 7. The designer hopes that the faucet’s special design brings users health and happiness. The faucet is made primarily of lead-free brass to provide safe drinking water, and the spout’s design takes the height and distance of water flow into consideration. A special inner structure makes it possible to use the handle to switch between hot and cold water, which saves space and makes the shape simpler and more graceful. An automatic shut-off function for hot water prevents it from accidentally running continuously.
