TWO WAYS OF WATER OUTLET: With a simple twist, switch between bubble water (which mixes air and water) and shower water (ideal for rinsing and cleaning). HIGH-QUALITY FOOD MATERIALS: The main body of the faucet aerator is constructed from high-quality copper, resistant to bacterial growth and wear; combined with rubber sealing rings, the interface is leak-proof; 22 galvanic layers resist various types of corrosion, ensuring durability and shine like new.
