Blue Eagle NP13 Disposable Face Mask is ideal for people who want convenient, comfortable, and protective masks for daily usage. Every mask in a 50-pack box is individually wrapped so that you can bring to everywhere you go easily and replace a new one whenever you want to. Our omega (Ω) folding design ensures good sealing and stability when you wear it. Also, we put an extra active carbon layer in our NP12K, so it can block unpleasant odor besides offering clean air. Otherwise, our thermal-bonded nonwoven inner layer provides a silky texture, so you can greatly avoid irritating and any uncomfortable feeling from the coarse plastic layer.
