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.
 
These mouthpieces are all new stock.  They may have the odd mark on the shank where they have been inserted into an instrument in-store and the box maybe a little tatty, but they are all new stock.
 
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.
