◇ If the sponge becomes dirty, the surface of the foundation will harden and it will be difficult to apply to the skin, so always keep it clean.
◇ When the sponge becomes dirty, use the separately sold "Shiseido Sponge Cleaner N" or dilute a mild detergent in lukewarm water and gently press the sponge to wash it. After rinsing thoroughly so that no detergent remains, drain the water and dry well in the shade before using again.
◇ If the case no longer opens and closes smoothly, please purchase a new case.
