Thank you for viewing! This is a black, two-mouthpiece case for tuba mouthpieces, made from Himeji leather! We've created a stylish look with elegant black cowhide, brown thread, and gold hardware. 【Regarding Usage】 It takes a little practice to insert the mouthpieces! However, because of this, the shank portion fits snugly, and the mouthpieces are unlikely to fall out even if you turn the case upside down with the lid open! You may need to use two mouthpieces during a tuba performance. I hope this case will be helpful in such situations. ※ Made by a leathercraft beginner in their second year as a hobby. Please check the photos carefully to confirm the condition and make your purchase with understanding! No claims, no returns, and no cancellations, please.
