My daughter loves this eye mask by Rocita , its all about unicorns at the moment so this was a must have .
soft and plush on the outside and the inside part close to the skin is made of silk, which is super soft, comfortable and breathable with an elasticated strap to hold it on. This fits me and my daughter so its definitely one size fits all
