PhoneLook Universal anti-migraine cold & heat therapy headband for adults

The wide and large headband features a gel on the inside that can retain cold and heat for an extended period. It can be used to reduce fever or as a relief for migraines, providing cooling on hot days when placed in the refrigerator or freezer. In winter or on cold days, the gel can be warmed by immersing it in warm water (maximum about 80 degrees), creating a soothing warmth. The flexible material allows the headband to fit any adult head size, although it is too large for small children. Key features of the product include the cooling or warming gel inside, the coverage of the entire head, and the 360-degree effect in a universal size for adults.
