I was trying to find a mask that would fit my 5 year old. Most children's masks are too big for him, I have to tie the ear straps and they are very loose around the face. These masks are the perfect size. However, when the ear strap is placed on my son's ears, they fall out of the mask. Also, the nose strip doesn't hold its shape, leaving a large gap at the top of the mask. However, my main concern is that the back of the packaging says "Not for antimicrobial or antiviral protection or related purposes, to prevent or reduce infection or related purposes", so it is useless for the school to protect themselves from COVID to protect!
