Effective Eye Relief Whether you're looking for relief from puffy eyes, migraines, headaches, or just looking to relax, the Cooling Eye Mask can help! Use our gel eye mask as a cold eye ice pack for puffy eyes, dark circles, headaches, migraines, eye strain, or as a hot eye mask to reduce puffy, dry eyes. Even when frozen at -18C, the flexible gel beads remain flexible and fit comfortably to the shape of your face. Features: 1. Double-sided double-sided design: One side is made of medical-grade plastic, and the other side is made of soft plush fabric, ensuring you the best safety while you sleep. 2. ADJUSTABLE & UNISEX: With an adjustable head strap, our hot and cold eye mask is sure to fit all different head shapes perfectly, suitable for women, men and kids. Designed for long hours of comfortable wear while you relax and rest, the firm fastener ensures that the cooling mask stays securely on your eyes even as you toss and turn in bed. 3. Cold and hot therapy: Just put the cold compress eye bag in the refrigerator for 2 hours for cold therapy, or put it in the microwave for 10 seconds for heat therapy. Use the plush side for a cooler experience, or the plastic side for an even cooler experience.
