Review (4/5): Great but slow shipping
I bought these as a gift. It's fine. exactly what I expected it to be. The only things I would bring up is the shipping was very vary slow, and then one I did get it, because the martial is what it is, it gets hot and skips off.
I bought it as more of a gag got so It's not really a problem.
But just a heads up in case you are looking for an inexpensive but worthwhile sleeping mask. Maybe keep looking as this one is hard to sleep in.
