Thank you for viewing. This is a tool for repairing dents that have bulged out on the outer end of a mouthpiece shank. It is exclusively for trumpets. We recommend using it in conjunction with the separately sold T-shaped tool. There may be scratches from the manufacturing process. The mouthpiece and T-shaped tool in the images are not included. Please purchase without commenting. Please refrain from comments asking for a price reduction. If you are interested in used or new mouthpieces, please search for "Net Brass".
