Purchased as a used item. The material is black resin. It is non-tunable. Size: Mouthpiece 28.5mmΦ, Body 24.7mmΦ, Total Length 590mm The previous owner stated they purchased it from the James Dominic Music website and had it shipped from Ireland. Performance videos can be found online. A case was not included, so I will include a handmade one. It will be packaged in the case, wrapped in bubble wrap, and shipped in a box. I may not be able to respond immediately to inquiries. I will reply in the evening.
