I'm selling a new item I purchased. It has been used, but there are no major scratches. Model: 31DW (no box) Inner Diameter: 17.3 Depth: Deep Throat: 4.3 Features: 31D wide rim ※From the official website It is probably a European shank. Retail price is 33,000 yen. Please refrain from purchasing if you are overly concerned about details.
