Love it. I immediately bought 50 more after trying it on my kid. She is 4 years old and fits perfectly. And the masks are soft, not like some of the other kn95s I've bought from Revain before. It also fits my 8 year old; but a little slower. I doubt it will work on older kids. The design is very cute and exactly as described. You will receive 5 to 10 masks with different designs, each mask is also individually packed. Considering the price and the delivery, I am satisfied with this purchase.
