Filtra 4-Ply Tie On Surgical Face Mask - Yellow 50 Pcs (BFE > 98%) TT-4YTM

Pros : Very good quality of the material used.The stitches and knots are perfect and fit in snugly on the face.Cons : Due to it's 4 layer it is little tough to breathe(thick mask). However if you get used to it then it shouldn't be an issue. Otherwise you can go for the 2 or 3 layer ones.

Very good quality, with industry standards.They are 4-ply masks.

These are very good and thick. Quality is much better

good however, rather tying it should have been a rubber band

V good product & through professionalism by Amazon as always

Sorry ... I have 2 boxes less.
