Black All Over Cotton & Poly Blend Facemask

This material is lightweight and the imprint of the design was clear and sharp. The fit is loose so if you like that, this is for you. I like how it's loose around the top and bottom (nose & chin). I love this custom design I made and shared it with friends to get some made for themselves. After washing, it has held up as well. PERFECT - just as I had designed it. Very clear and sharp.

Black All Over Cotton & Poly Blend Facemask
Zazzle Reviewer Program
My review is from all of my mask. Out of 40 of them I have had issues with 1 never receiving even after 2 weeks even though I paid for a year for Zazzle Black. 1 it took too long to get here and it’s way to thin for my liking. 4 even though the straps were for Standard Adult size it was too small and pulled ears forward. My pictures are of 3 of the 40 mask.
Overall these mask are a good fit. I have Asthma and Claustrophobic issues. I have tried other different style mask from homemade ones to the hospital ones and they all make my claustrophobic and asthma worse. These Poly Cotton blend mask do NOT bother me. The printing turns out ok on each one. It’s NOT bold or popping in colors.
