◇If the sponge gets dirty, it will be difficult for the foundation to stick to your skin, so please keep it clean at all times. ◇When the sponge gets dirty, apply about 1mL (slightly larger than a 10 yen coin) of "Shiseido Sponge Cleaner N" (sold separately) directly to the dirty area without wetting your hands or sponge, gently rub the sponge with the pads of your fingers to blend it well with the dirt, and gently press and wash with water or lukewarm water. After rinsing thoroughly so that no detergent remains, drain the water and dry well in the shade before using. ◇If the feel or finish of the sponge becomes poor, please purchase a new sponge. ◇If the case no longer opens and closes smoothly, please purchase a new case.
