The Cuomo face-mask is designed to fit every face properly from cheekbone to chin. Soft hand-ties make sure the masks stays on securely, as we know fit is one of the most important factors in a face-mask. Made of 100% sustainable Portuguese cotton poplin and cotton jersey ties, this mask should be machine-washed on warm (in a delicates bag to protect the ties) and then dried thoroughly to remove whatever residual moisture may be on it. Bacteria LOVE moisture. We also recommend hair dryers (!) if you don't have a clothing dryer at home.
