Purchased a few months ago at Hattori Wind Instruments in Nishisugamo. It cost around 160,000 yen. This particular piece has a lot of character, with a thick, full sound. I'm selling it because I'm switching to a different mouthpiece. I believe that, being a vintage item and used, it won't depreciate much in value, so I've set the price close to what I paid for it. I purchased it after speaking with a trustworthy staff member at Hattori Wind Instruments and actually trying it out. It is a genuine item, and was originally (though I wasn't told the name) owned by a top professional that everyone knows. Comes with the original box. ※ I found that Hattori Wind Instruments is selling it on Mercari, so I've added photos. I bought this exact item there.
