For over 350 years the Japanese company Ichihana has manufactured spray lances made of high-quality muntz metal, a forgeable brass alloy. The hand hammered brass quickly takes on the body temperature and has an antibacterial effect due to the high copper content. The holes are etched from both sides in a special process, which creates an hourglass shaped cross-section. This type of manufacturing permits an extremely fine and precise spray. With plug system for hose couplings.
