Product Description:This mask will block out the light - perfect if you want to relax, are taking a long flight or live in a brightly lit area. It will not seal around your face and leave marks but when you close your eyes, the black felt layer inside the mask ensures darkness. Made in Harris Tweed and lined with a pink cotton that will be soft on your face. I use a wide elastic for the fastening and, to be sure of a good fit, offer the mask in two sizes, small (20 - 22") and medium (22 - 24") - do let me know if you need a different size. Measurements should be taken around the head at eye level).
