As an effort to help people combat the spread of COVID-19, Elicto brings you these Washable 3D Masks. Different from common masks whose working principle is using multilayers to build a net structure to block dust, this sponge mouth mask is made of polyurethane which itself is a 3D network structure. It has a dust blocking rate of up to 99% and offers a strong defense against pollen, bacteria, virus, dust, and mold particles. This mask is incredibly soft, thin, and breathable so you can stay comfortable and protected. Every 3D mask is strictly disinfected and sterilized by broad-spectrum automatically and disposable vacuum packing.
