We own these Kids 4-Pack Washable Reusable Face Masks. They’re awesome and have held up great after being washed lots of times. They come in little kid and big kid options. I bought the little kid ones because I didn’t want them too big on my 7 year old and they are a bit tight. I would probably recommend big kid for kids 5 and up! 17% off making the pack of 4 under $10!!
