Review on Breath-Supporting Silicone Insert Bracket: Enhancing Comfort and Airflow by Jathan Louis

I'm having trouble breathing so I tried them and some of them worked. It doesn't look like I'm breathing with a sheet mask. I wouldn't say it's an anti-fog product for glasses, but it helps a little. I see others saying they are too small but for me, a 24 year old male, they are good and fit my mouth and nose perfectly. The parts that tie into the mask straps relieve my ears and allow me to hang the mask when not in use. It's cold where I live, but I think they're a bit warm because the hot air I'm generating bounces off. wearing a mask. In general I like it. I gave the other 3 to my family and washed them every day.
