This is a Claude Lakey alto saxophone mouthpiece. The opening is 4*3 (1.91mm). There are no noticeable scratches on the tip rail or table. It's not like new, but it hasn't been used excessively and is still in good condition. I think it's a rubber mouthpiece that can produce both flashy and mellow sounds. How about it if you want to try it?
