This is a Schmidt Digital Series 8 mouthpiece. The shank is European. Rim inner diameter: 17.5mm Cup: Normal Bore: 4.1mm Retail price: 18,700 yen It responds more lightly than the standard 8, but some people may find it a bit shallow. There are no scratches or dents, but there is some dirt due to storage. Since there is no box, it will be packed in bubble wrap and shipped. If you need more clear photos, I will send them. Thank you.
