Prototypes for sale  

I have been designing and manufacturing mouthpieces on my in-house printer farm all spring and summer. I have made over 100 mouthpieces. Some are finished products and have been sold, some I have kept for my own use. But, I also have a bunch of prototypes. Not all of them are totally polished and a few have cosmetic flaws, but the ones that I have kept are excellent mouthpieces with great tone, response, and intonation. It makes no sense for me to keep them, so I will be offering them for sale here, at highly reduced prices.

I got some blue resin for my SLA 3D printer. This is the result - except I made eight of them. I used the S4M design. They play great, and they look, well, blue! Maybe you'd like to have one of them!
