Thank you for viewing. I purchased this here before, but it didn't suit me, so I'm putting it up for sale. I used it for testing about 1 or 2 times. There are some marks on the shank, but I think it's in good condition. The box is included, but the lid is slightly torn. Rim inner diameter: 17.45mm Throat diameter: 4.5mm Shank: ES (Schmidt shank) U cup. The rim is an A rim, which is rounded and has a soft feel. The weight is the traditional heavier type. The list price is 30,800 yen.
