10cm Black, Green This is a mask band that reduces the ear pain that can occur when wearing a mask for long periods. It fastens by clipping the mask's elastic bands with snaps. The position of the band is up to you, but wearing it higher on your head will reduce the strain on your ears. We understand that comfort is subjective, so we recommend trying on your mask and stretching the elastic to see what length works best for you. This mask band can also be used in various other situations. It is firm but washable. As it uses interfacing, please avoid high heat when ironing. #maskband #earpainrelief #maskhook #forkids
