Thank you for viewing. Please read the profile. Thank you. JK Exclusive 2DM A1 Silver-plated body, gold-plated rim & inner Standard shank Used item Rim inner diameter: 2 (17.5mm) Cup depth: D (medium) Cup shape: U cup Purchased on Mercari in January 2024 for 12,000 yen. There is some wear and tear, but it is in a clean condition with no scratches or shank distortion. The shank is a standard shank and seems to be compatible with both American and European models. I think it is a standard model in terms of mouthpiece size. Only the mouthpiece itself, no box. I am selling it at a special price personally to clear out mouthpieces I am not using, so I will not be lowering the price for the time being. Thank you for your understanding. Returns and refunds are not possible. Please ask any questions before purchasing.
