Please note that I do not offer approval / testing on these mouthpieces, so please ensure you know what you are ordering when placing an order.
 
I find mouthpieces impossible to take photographs of due to the reflections, so the image shown in the stock image from Perantucci.  I am happy to supply additional images if you send me a message.
