The advertising is misleading the pictures make it look like a 3d printed hard mask and yet it's made out of some kind of cheap cloth. It doesn't fit right it pulls down on the nose so it closes your nostrils and slides off your face when walking easier then any other mask I've used because of how it's secured at the neck. I just used it once going to work in the morning and I could start seeing it fray because of how crudely it's cut out. The design is very flawed and cheap. I read the return policy and it says nothing about faulty product return. They refused return refund so I have to plead to PayPal.
