This is a no-brand, large-shank mouthpiece. I used it occasionally for trombone and euphonium, but I haven't used it much lately, so I'm offering it for sale. I hope someone will find it useful. It hasn't been used much, so I think it's in near-mint condition. Please refrain from purchasing if you are looking for a perfect item or are overly concerned about minor details, as it has been stored at home. Thank you.
