We advocate “one thing multi-purpose”, under the premise of tray as the base plate, designed a number of different shapes, different specifications of ceramic ware, glass products, natural stone and wood products. They have a subtle relationship with each other, and can be flexibly interactive in the base plate to make different collocation and present different functions. Its functionality can cover the Serving Dishes, Sharing Platters, Bento Boxes, Bread Baskets, and in-room Amenity Dishes.
