This knock-down mask is multi-functional, which is made of 100% cotton material plus 0.25mm pet material, no filter on the mask, you can choose just wearing cotton mask if you do not need clear face shield, but if you need both when you go out, this is the best choice. Both Adult and Kids size are available, the price on my site is for adult size, but if you need kids size, and you can add your logo on the mask if your quantity up to 1000pcs or more, pls kindly send your inquiry for exact price.
