Customer received a foil stamped greeting card with this imprint.  She would like to replicate the font for a thank you card. I've done a reverse image search to find the source of the card with no success. I've also tried the following monoline scripts: Alfons, Hustle, Cosmopolitan, Kingbirds, Smoothy, Nickainley, Felician, Thirdlone, Campground, Good Time, Bowline, Bundt Cake, and Beloved.  I've tried some more similar ones. I don't really think it's handwritten due to how clean and concise it is, but I've had no success finding what font it is.

I have had no luck in finding it and so it could be bespoke. 

I've a feeling that's the case as well.  Nothing seems to completely match up.
