It may feel rough when it touches your skin, but there is no problem with the quality. ◇ After use, close the cap properly. ◇Do not leave in direct sunlight or in places with high or low temperatures. ◇The container can be used as is, so after using it, remove the inner container and set a special refill (sold separately) for replacement.
