I NEVER USED A SLEEP MASK UNTIL NOW BUT I DECIDED TO TRY ONE SINCE I HAVE PROBLEMS WITH LIGHT AND MOTION GIVING ME A RESTLESS SLEEP. I AM SURPRISED AT THE DIFFERENCE IT MAKES. IT IS SNUG BUT NOT TOO SNUG AND IT STAYS PUT ON MY HEAD WHILE SLEEPING WHICH I DIDN'T THINK IT WOULD. IT IS MADE OF PILLOWED SILK AND FEELS WONDERFUL. I THINK THAT IS WHY I DIDN'T TAKE IT OFF. OVERALL THIS IS A GREAT VALUE AND DEFINITELY WORTH THE LOW PRICE. I DO RECOMMEND AND WELL DONE TO THE SELLER!
