This set contains four STURM NANO-SILVER MASKS: A soft, washable, and reusable face covering made with anti-microbial, anti-friction, nano-silver-infused fabric that has also been shown to have anti-bacterial benefits for the skin. The material and technology were chosen because of its soft feel and lightweight, breathable fabric that prevents glass fogging and avoids inflammation-inducing chafing against the skin. With a comfortable fit, each face mask features adjustable ear straps, an adjustable nose bridge, and the Sturm logo. All masks are not for medical use, but rather as a safety device for personal, non-professional use.10% from the retail price of every STURM NANO-SILVER MASK sold will be donated to the World Health Organization’s Covid-19 Solidarity Fund.A soft, washable, and reusable face covering.Made with anti-microbial, anti-friction, nano-silver infused fabric.Breathable fabric that prevents glass fogging and avoids inflammation-inducing chafing against the skin.SKIN THERAPIST TIPThe masks are made to prevent ‘maskne’.
