The stainless steel surface has been processed similar to the damage treatment of jeans to create a distinctive worn look.
Aoho Seisakusho is the worlds first stainless steel processing technology. As a vintage look, there are uneven imperfections and scratches on the surface.
When using it for the first time, please use a scotch sponge with a cleanser and wash thoroughly before using.
Note: If the sponge scrubber is dirty, the smell of the dirt may adhere to the main unit. Use a clean sponge scrubber.
