Review (1/5): Too small! Hard plastic! Not soft silicone, as described.
These kids' mask brackets are suuuper small, even for kids. My kids are 6 and 11, and the brackets are so small that they pinch into their mouths. Maybe they would be appropriate for a 3 or 4 year old? Also, they're advertised as silicone, but they are just cheap, brittle, hard plastic. Very uncomfortable to wear - they dig into the skin. The one positive thing about these brackets is that they have small notches on the side that hook onto the pleats in disposable masks.
