[Luxurious SUS304 Stainless Steel & Excellent Durability] High-quality "SUS304 stainless steel" is used for the main body material. Unlike general resin (plastic) adapters, it is difficult to break even if dropped and is resistant to rust and corrosion. It has a clean appearance, is resistant to mold and dirt, and can be used hygienically for a long time. [Stylish Design that does not detract from the bathroom's atmosphere] It goes perfectly with metal-tone shower heads and stainless steel hoses. Attaching a resin adapter in between can often disrupt the sense of unity in design, but with this product, it blends in seamlessly without feeling out of place, and does not detract from the luxury of your bathroom. [G1/2 Standard - Compatible with Major Manufacturers] The mounting screw size is the international standard "G1/2". It is compatible with shower heads and hoses from many manufacturers that adopt the G1/2 standard, such as TOTO, LIXIL (INAX), SANEI, KAKUDAI, and Tanaka Kinzoku Kogyo. *Please be sure to check the screw size of your home shower hose before purchasing. (Not compatible with special standards such as KVK and MYM, or requires a separately sold adapter).
