Terrible product, terrible service. They sent me the wrong sizes and are giving me a hard time about a refund--and they're telling me that I have to pay for shipping back to China, though there was no information provided that this was a product shipping directly from China. And I have no promise that they will refund me. Cheap, poor quality and it cost a FORTUNE. Masks don;t stay on-they slip and fall. Gotta love these people, taking advantage of people during a pandemic.
