About this Project Multifunctional: This is a functional eye mask that can be refrigerated as an ice pack. It can also be used as a warming eye mask, heated in the microwave. Use on eyes, face, or forehead for relief and treatment of dry, irritated, or swollen eyes, dark circles, tension, bruises and muscle aches, sinus issues, migraines, allergic irritation, and other eye problems. Easy to Use: Seal the eye mask in a plastic bag and place it in the refrigerator's ice compartment. Chill for 1-2 hours, or freeze for 30 minutes. Alternatively, microwave for 10 seconds at a time to warm the mask. This gel pack stays cool for 15-20 minutes, and the optimal treatment time is approximately 15 minutes as recommended by doctors and therapists. Usage: When feeling tired, tense, or experiencing a migraine, the cool eye mask can soothe you and help relieve pain. This eye mask is suitable for women, girls, students, or office workers who sit in front of a computer for extended periods; or those who stay up late, have dark circles, and experience dry eyes. Reusable: Filled with massage gel beads and glycerin, the cool sensation lasts longer. It's super soft and features a breathable plush backing. These gel eye masks are FDA-registered, latex-free, and non-toxic. 100% pressure tested, no breakage, no leaks, long lifespan.
