The sleep mask saves the quality of sleep even in bright conditions. All sleep masks have a darkening layer in between and the mask has a flexible, soft-grip rubber band, making the mask suitable for many sizes. The size suitable for children can be ordered from all the sleep masks on sale. You can order a child's sleep mask either by sending a message or by ordering a mask normally and then at checkout you write in the additional information box that you want to order a mask in the child's size (age should be mentioned).
So get to know, for example, wonderful linen sleep masks and get yourself a feather-light sleep.
