Thank you for viewing! Romera Brass Samurai mouthpiece with case! Inner diameter: 32.50mm Throat: 8.25mm Depth: 45.0mm Universal shank From the signature series of mouthpieces by the Spanish brand "ROMERA BRASS," this is the "SAMURAI" model for B♭ and C trumpets, designed for Mr. Shimpei Tsugita of the Yomiuri Nippon Symphony Orchestra. Includes a leather case. I purchased it about two years ago and haven't used it much, so I'm selling it to declutter! I don't have the receipt from DAC, so I don't have proof, but it was a selected item!!! The sound I get when playing it is crisp, and the sound comes out a little louder compared to other mouthpieces! Please check the condition in the photos! I'm asking for no claims, no returns, and no cancellations, so please purchase only if you are satisfied with the condition!!
