Not just the quality of the mask that I would give 5 star, its the quality of customer service that deserve it. I'm from UK and I'm deliberately ordering the "Made in Hong Kong" masks because I trust the quality and would like to support HK people.
I place an order on 4 Feb and received my order on 12 Feb. Well packed, speedy delivery. They even gave me a choice of 3 different shipping companies to choose which offer different type of service.
Keep up the good work!!! Support from the UK HKger!!!
