Touch a lot and enjoy the changes over time The trays are manufactured by hand one by one, from cutting out the board into a circle to squeezing the spatula to raise the edge and polishing the surface. We aim for a soft look that is a little different from the one extracted by the machine. In addition, the tray is not treated to prevent discoloration, so as you use it, the surface oxidizes and gradually changes to a calmer color. By layering this, a deep flavor will come out, so take the time to develop it into one dish that is just for you. < Product Contents> Starter kit for trays 120 × 6 pieces 1.
