【Product Description】 This is a beautiful condition JK (Josef Klier) mouthpiece, supervised by Stefan Dohr (principal player of the Berlin Philharmonic). I purchased it during my stay in Germany. I tried playing it a few times, but found it difficult to switch from the model I've been using for many years, so I've decided it's not for me and am putting it up for sale. 【Shipping】 I am currently preparing for a temporary return to Japan, so the earliest possible shipping date will be March 16th (Monday) or later. We would appreciate your consideration with this in mind. 【Specifications】 Model: W 2EM 4.2 S.D. (Dohr Model) Inner Diameter: 17.5mm / Bore: 4.2mm Rim Shape: W (Wide Rim) Cup: Deep EM Cup 【Condition】 As it has only been tried a few times, there are almost no shank scratches, and no dents or distortions on the rim, making it in excellent condition. It has been cleaned and disinfected before listing. The box is not included, so it will be carefully packed with cushioning material for shipping. We hope this will be considered by those looking for a Dohr model or a stable wide rim. A high-quality French horn mouthpiece with a precise design to improve tone. - Model: JK 2EM - Model: 2EM 4.2 - Model: M 4.2 S Thank you for looking.
