If you previously purchased an XL-D and need a spare mouthpiece, I still offer made to order parts for them.


Remember – I am not a machine – as a 100% handmade quality each will vary slightly. Tube manufactures are not perfect either – all lengths and diameters are general references and may slightly vary per piece.  😀 – Thank you!
