Thanks for reaching out. I am a great fan of the toddler mask for my two kiddos, so I decided to try the adult masks. I ordered the white ones first, liked them. Then as COVID went on the rise and not having N95 masks I noticed the black Level 3 ones and ordered them. I received them quickly and the package states they are 4 layers. The only down fall is they are very itchy and alittle loose, but am grateful to have them. The price is right as well...
Thank you.

Dear Sarah,
Thank you very much for the detailed feedback! A special gift will be sent to you soon. Although we haven't heard from other customers about the downside of the Stealth Black masks, we will definitely let our business partner know, and see if they can make improvements. We recommend you try ASTM Level 3 surgical mask on our website if the color works. Many customers said it's soft. Thank you for shopping with us!
