The StringKing 2-ply reusable Cloth Face Mask uses two layers of premium cotton fabric to create a CDC-recommended washable cloth face mask for daily use by kids and adults. The StringKing Cloth Face Mask is made in the USA using American-made Supima cotton fabric and nylon-elastane elastic string ear loops for a soft, comfortable feel. StringKing fabric face masks follow the CDC recommendations for cloth facial coverings to help slow the spread. These face masks are not medical-grade surgical masks or respirators.
