This is a cotton mask with 3 layers of protection. The mask is designed like the N95 mask and comes with a light metallic nose clip and elasticated ear loops. Each pack contains different colours of masks to offer more colour choices. The mask protects against dust and pollutants. It provides comfortable wearing and its design and colour adds to the style element. The colour choices are being provided based on need of the people to have more colour options rather than packs having single-colour masks. Buy these N 95 shaped protective cotton masks online and you would never want to stop wearing masks for want of colour options. Free shipping is provided on every order.
