¥◇When the cartridge is empty, immediately replace it with a new cartridge (sold separately). (If the cartridge is left empty, the tip of the brush will dry out and the liquid will not penetrate as well.) ◇If the product gets on your clothes, it will not come off, so be careful not to let it get on your clothes. ◇Do not store in direct sunlight or in a hot place. ◇Always close the cap after use. ◇Because it dries quickly, if you leave it unused for a long time even with the cap closed, or if eye shadow or foundation gets on it, the tip of the brush may dry out and become hard. In that case, press the push button slowly several times to soak the brush in the liquid, then carefully wipe the tip of the brush with tissue paper. ◇Be careful not to get the liquid in your eyes, and if it does get in your eyes, rinse them immediately. ◇Due to changes in temperature or air pressure (such as boarding an airplane), the liquid may overflow when you use the product. If the liquid overflows from the tip of the brush, wipe off the excess liquid with tissue paper and adjust the tip of the brush before using it. ◇When the brush has become hard or the tip of the brush is filled with liquid, if you press the push button, liquid may accumulate and come out from the base of the brush. This does not affect the quality of the contents, so please be careful not to let the liquid drip. ◇Do not wash the tip of the brush with water. ◇If the cartridge cannot be fixed smoothly or the brush has become hard and cannot be used, please purchase a new product.
