PLAIN MATERIAL Non-medical face mask/covering (this is only a face covering and not a medical face mask), in a variety of cotton materials, with elastic ear bands which can be re-knotted to adjust size. Elastic may be black or white depending on availability. The material face covering is one size - 'medium adult' which seems to fit most people ,including 'teenages'; unless stated (small or large) in colourway options. Approximate measurements 15cm heigh x 23cm long. Made from beautiful 100% cotton material, such as Liberty lawn cotton, Laura Ashley, Sandersons (some occasionally are poly/cotton). All internal seams are DOUBLE sewn, to ensure that they can be washed again and again making them more durable than most. The mask is made of a double layer of good quality cotton material. This item can be washed at 40-60 degrees. Air dry normally, iron if required and re-use. Theses are eco-friendly masks which are washable, not disposable. These coverings are for short period use only. I have made my masks to be as ‘natural’ and eco-friendly as possible. Free - speedy delivery in Hitchin. Can be posted out. Once they come to the end of their natural life they can be recyled/go in the compost bin - not landfil.
