2 Layer, Cotton Back, no poly fusing. Comfort Elastic Earpiece. We promised to provide them through the end. Here we are, a year now later, and still providing quality masks, that are comfortable, and help in some capacity. Thank you for being a part of this journey. I hope you are smiling under these, as we all hopefully turn a corner this year. One size fits most. New collection of colors to match our pieces. Ships 2nd week of March.
