Review on Poyiccot Plastic Passport Protector Transparent by Nathan Unruh

I bought them for me and my colleagues for our trip to China. You are expected to carry your passport with you 24/7 in China. But anyone who has ever been to southern China knows that it is very hot and humid there. These covers have helped keep all of our passports nice, clean and sweat proof. As an added bonus, you get a pocket on the back when using this case. I have used this bag so many times! I was able to store my boarding passes, ferry tickets, baggage claim, etc. there. Great little product. Good bang for your buck.
