My sleep essential: Dongkook Pharmaceutical Good Sleep Steam Eye Mask

I recommend Dongkook Pharmaceutical's heat eye mask, my favorite sleep item. Office workers often use their phones or computers, which easily causes eye fatigue. So I always wear a heat eye mask when I sleep. As soon as you open it, heat and steam start, helping to relieve tired eyes in about 30 minutes, which I love. The heat-generating ingredients used maintain heat and steam for 30 minutes, helping you fall asleep quickly while wearing it. It is very lightweight, fits comfortably when worn, and is hygienic because it is for single use. Also, it's easy to carry, so I always bring it when I travel to get better sleep. If anyone has trouble falling asleep easily, I recommend Dongkook Pharmaceutical's heat and steam eye mask!
