Greg Black New York 5.75 M - Brand: Greg Black - Model: New York 5.75 - Size: Medium I purchased this new and used it for about two months, but I've switched back to my previous mouthpiece, so I'm selling this one. It has a rim equivalent to a 4G (4.5G in Greg Black terms) and a cup slightly deeper than a 5G. There are no dents or scratches on the rim or shank. It will be shipped in the included clear case. New price: ¥57,200 Price negotiations are possible.
