Not worth Even the Cheap Cost
I have had multiple styles of sleep masks. This one slips right off. It also has a weird dent on the forehead area, so light just seeps in. It also doesn't have adjustment features, just velcroes onto the head, but no sizing features. Don't buy. There is a star pattern sleep mask that is $6-$8 on Amazon that has stayed put, keeps the light out, with a sizing strap. Buy that instead.
