Our non-medical grade face masks are made with Stance’s premium Butter Blend™ fabric to maximise your everyday comfort. One size fits most, washable and reversible (please clean between each wear). Keep covered, comfortably. The Face Mask should not be used (1) in any surgical setting or where significant exposure to liquid, bodily or other hazardous fluids, may be expected; (2) in a clinical setting where the infection risk level through inhalation exposure is high; or (3) in the presence of a high intensity heat source or flammable gas. Stance, Inc. makes no warranties, either express or implied, that the mask prevents infection or the transmission of viruses or diseases. The Face Mask is not a substitute for professional medical advice, diagnosis or treatment. If you have any specific questions about any medical matter, you should consult a doctor or other healthcare provider.
