All Sharmen J. Beauty masks are 100% cotton and includes a filter and nose band. Tie knots in the ear bands, if needed, for a customizable fit so that the mask will lay as flat as possible on your face. The chin is adjustable by tucking it under. Hand wash only with soapy warm water, rinse then gently squeeze the water out without twisting or turning the fabric, then hang to dry. The face mask has a nose wired securely incased. Daily sterilization recommended. These are not medical grade masks. The masks don't guarantee full protection or provide 100% coverage from a virus. The CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g. grocery stores and pharmacies) expecially in areas of significant community-based transmission. -Due to high demand, your order will ship within 5-7 BUSINESS days.
