Two commercially available boxed tissue boxes can be stacked and stored. The design reflects the sunset at the end of summer seen from the cape of Kasa in Kaga City, Ishikawa Prefecture, and mixes with the color of the sea. The lid is a gradation of orange, and the body is painted with a change of light shining into the sea. When two pieces are stored, the lid lifts up, and the part where you can see the change of the lower body body increases. It is a product that allows you to enjoy the change of color.
