Review (1/5): These cheap masks last about 2 months before they're useless.
These are a COMPLETE rip off! I've had to replace EVERY single one of these within 2 months.
1. The stretchy string wears out quickly. You can extend your use of the mask by tying a knot in the strap, but the string will continue to stretch and eventually it won't fit an elephant's head let alone a human's.
2. The dye stains our sheets! God only knows what the dye is doing to your eyes.
3. The price is outrageous! You can buy a HIGH QUALITY sleep mask for less than HALF of what this one costs.
