Disclaimer : Our face masks simply adds a physical barrier to your face. At the very least, they serve as a reminder not to touch your face. We are looking to add additional filtering abilities in our mask designs as supply chains open up. If you happen to have an N95 mask, you can use our mask as a cover to get more longevity from the underlying mask. Place your mask over another mask, or our mask on its own. Either way, you will be adding a level of protection, comfort and style. Our masks are washable so they can be reused, making them an excellent value.
