Review (5/5): Really in good quality.
Shower caps are really necessary for people like me, who has extremely long hair and do not want to wash hair every day. The rubber band is tight so I don't need to worry that the water would come into the caps.
It is more convenient than the rubber headband for make-up. I used to use the headband when I have a facial treatment, but the liquid always goes into my bang. But I don't need to worry about when I use the shower caps.
There is only one disadvantage, it's too much! I think 13 caps can be used for 10 years.
