Joseph Alessi by Griego Trombone Mouthpiece 6C Green Gold [Model] 6C [Cup Inner Diameter] 26.20 [Depth] Standard [Shank] Large Shank Retail Price: ¥46,500 USED 中古品 (Used Condition) Thank you for viewing. This is a Joseph Alessi by Griego 6C. It appears to be the rare green gold model. As it is currently sold as an artist model, I believe this is the previous model, which is no longer sold. Please refrain from purchasing if you are sensitive to used items. The room is reflected in the image, so I have made some adjustments. If you would like more photos, please comment and I will take them. Thank you for your consideration.
