12cm Navy, Gray This is a mask band that reduces ear pain that can occur when wearing a mask for long periods. The mask's elastic is held in place with snaps. The position of the band is up to you, but using it higher up on your head will reduce the load on your ears. Comfort is a matter of preference, so please try wearing a mask and stretching the elastic to see what length works best for you. In addition to mask bands, they are used in various situations. It is stiff, but can be washed. Since it uses interfacing, please avoid high heat when ironing. # Mask band # No ear pain # Mask hook # For children
