Claude Lakey alto saxophone mouthpiece. It's a 5*3. I bought it and played it a few times, but I'm not used to jazz and couldn't play it well, so I'm selling it. The mouthpiece patch has been replaced with a new one. There's also a spare. This alone costs nearly 2000 yen, so it's a good deal! (Lakey has a special one that fits the indentation). The ligature has some minor scratches, but overall it's clean and almost like new.
