Thank you for viewing. This is the Gerd Seifert model from Tilz, a well-established German mouthpiece manufacturer representing Europe. SB4T (17.0mm / 4.0mm / Medium depth / Medium wide) Standard price (tax included): 14,300 yen European shank. I purchased it new. I am selling it because I accidentally bought the wrong model number for the mouthpiece I wanted. The box is tattered, but I only used it for testing. It has been cleaned with baking soda and disinfected with alcohol. **Please note that the contents are clean, but the box is damaged.**
