Warm eye mask for eye strain

As you can see, this is a Japanese product. It’s not just a simple sleep mask; it’s a warm eye mask designed for when your eyes sting and feel tired, like when you read a lot or haven't had a good night's sleep. You can also use it during long flights or long-distance travel. I have a lot of books coming in lately because of my certification exams, so it’s great to wear this when I feel fatigued.
