Selling because the size didn't fit. Used only for testing and a little more. No box, no price reduction. 〈Quoted from the manufacturer's website〉 Inner rim diameter: 15.90mm Throat: 3.65mm This is a used item, so no claims and no returns are accepted. Please note that the packaging may be reused cardboard. (Depending on the situation, the shipping method may be changed from Rakuraku Mercari Bin to Yuuyu Mercari Bin.) Also, I have posted images that make it easy to understand the condition of the item, such as scratches. However, since this is a used item, please refrain from purchasing if you are concerned about the condition of the item or the packaging.
