Handmade large brass plate by Japanese craftsman Ruka Kikuchi (aka Lue). He makes this flatware by hammering a cut sheet of brass metal, rounding up the sides so the vessel can hold small sweets and other snacks.

As time progresses you'll find that this dish will patina and darken as the metal oxidises, also reacting to the natural oils on ones hands. Each is unique, featuring little scratches up-close where the craftsman has been at work.
