Customer service only operates through email. No human contact. Customer service admits that I received 4 masks that were not sized properly. They are too big to wear. They informed me they do not give refunds and then disappeared. At some point they offered to replace one but I have four of the same and questioned if they could replace four with proper design and size. Havent heard from them since. Their phone number is no longer a working number. User's recommendation: Do not order from this company.
