A night of sparkling and freezing cold winter vapor. The luster of the silver foil itself, the dull light of sulfurized silver foil, and the colors of the mineral pigments are combined. 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 lighting at night. The foil is coated to prevent discoloration, but the color will gradually change over time. We hope you will enjoy this change as well.
