This soft elastic is just we needed to make masks that my kid would keep on! Its just like the type used in the disposable masks and has held up to both being sewn into our masks and going through multiple washes! I was initially concerned about the latter, that it might disintigrate or fall apart but it has held up great! Its soft and only gently pulls as it stretches so it theres no pain even when wearing the masks for a whole day. I do wish it had more color options but can't complain at all about the functionality!
Pros: Stretches, can be washed, can be dried!
Cons: Lack of color options, otherwise nothing else!
