◇If the case cannot be opened and closed smoothly, please purchase a new case. ◇If the puff gets dirty, it will be difficult to apply, so please always keep it clean. ◇If the puff gets dirty, use the separately sold "Shiseido Sponge Cleaner N" or wash it by lightly pressing it with a mild detergent diluted with lukewarm water. After rinsing thoroughly so that no detergent remains, drain the water and dry well in the shade before using. ◇ Please note that it may break due to impact such as dropping.
