Available in packs of 10 or 50 depending on your needs, these KN95 respirator masks are ISO Certified, FDA Certified, and CE Certified. As a manufacturer of composites, we use PPE everyday to stay safe. We have trusted suppliers that we have used for years, and have imported these masks in bulk from China to serve those in need. These face masks are not intended for medical purposes, but are great for other essential businesses and individuals who choose to be in public. We can import up to 50,000 more within a weeks notice for those in need of larger bulk quantities.
