We luxuriously used 6A top-grade silk 100% fabric. Let's start an easy night care habit to get "beautiful while sleeping" with silk, a natural beauty material that contains ingredients that are good for beauty! It has excellent heat retention and moisture absorption and desorption, and can be used comfortably throughout the year. The texture that cannot be achieved with chemical fibers cannot be let go once you experience it. Eyes that have been overworked by long hours of desk work or smartphone use are gently healed with the moist and soft touch of silk. It fits comfortably on the face with a moderate sense of weight. The moisturizing effect of silk also prevents dryness around the eyes. The filling material is a gel type, and can be used hot or cold. * It cannot be frozen. ■Approximate heating time■ 500W 30sec (It depends on the outside temperature, but the approximate duration is about 10-15 minutes) [When used cold] Remove the inner bag from the cover, put it in a plastic bag and chill in the refrigerator for 1-2 hours. Please set it on the cover before use. Available in 4 colors for each personal color that is popular now. You can choose the color that suits you, as well as the color of the person you want to give as a gift. I think it's refreshing that the choice of color is approached from a personal color. The package of illustrations with seasonal flowers on the girls inspired by each color is easy to choose as a gift and you will buy a package without thinking!
