We have not used them yet because we have not been out, but they are very comfortable. We hopefully will be able to make doctor’s appointments soon and will feel comfortable knowing we are staying as safe as possible for everyone’s sake.

On some you might want to add a small piece of interface at top of nose area. If the customer wants to add a piece of pipe cleaner for a seal above nose. Your current pattern leaves very little open space so that is not really an issue. Thank y’all so much for what you are doing.
