■ Mark Curry Back Trumpet Light Heavy Bottom Cap x 1 【Description】 ★ This part was purchased new from an authorized domestic online shop. ★ I do not own a BACH trumpet, so I cannot comment on the feel or playability after installation. ★ Unused item. ★ There are some minor scratches and dullness on the surface. ★ Weight is approximately 29 grams (see image). ★ Although it is a bottom cap for BACH, it may not fit all Back trumpets depending on the model number, year, and model. Please be aware that we cannot offer a warranty or refund if you force installation and damage the screw threads or the instrument itself. Please do so at your own risk. ★ We will ship quickly and carefully via the post office.
