The real elastic for masks – 80% nylon – 20% spandex

20% spandex – 80% nylon. The real deal! Watch the video below! Soft for the skin. PLEASE NOTE: We also do not sell these on rolls. We cut them in lengths of 5 and 50 yards in small bags, cheaper to ship. That way, we can serve as many home sewers making masks as possible. However, we have something others do not have: stock and fast service! Check out the video to see the elasticity. If you are making masks, please visit our HTC line of interlining and interfacings of non woven, as many of these products are used right now to make masks. https://monfil.ca/product-category/ontheside/htc-en/
