Early spring with cold weather. Silver foil is sulfurized to bronze, and the colors of spring are layered on top of it. Since the foil is used, the expression changes depending on the type of light and the angle from which the light shines, such as morning sunlight, evening sunlight, and warm evening light. The foil is coated to prevent discoloration, but the color will gradually change over time. We hope you will enjoy this change as well.
