Review on Breathing Protector: Silicone Internal for Enhanced Airflow by Mark Kolipano

This mask holder is suitable for disposable mask. I bought it for my BYOM cloth face mask, it's too small for that, it moved the face mask away from my face allowing all the outside air to pass through. I didn't like the feel of the silicone on my face. I prefer to feel the fabric. I returned them for a full refund, thanks.
