I purchased this about two years ago. I used it about three times and then stored it at home. I like headbands, but they usually give me a headache, so I gave up on them. However, this one alleviates the pressure considerably, so I can wear it without stress. The color is black, and the widest part is about 3.7cm. Please consider this item as a used product. I am not considering lowering the price at this time. Please consider it if you are interested ♪
