Includes 6 cute tie dye masks that fit my 4 and 7 year old granddaughters very well as does the elastic on the ears It has one adjustable strap that makes it easier to fit better. They are made of soft cotton, very comfortable on the ears and breathable. So far these are the best baby masks we have found for girls sold here in local stores are not too big and there is no way to adjust them they are like a corrugated box very happy with my purchase. highly recommended.
