This a bellows-mending shop, and its proprietor - Francis Flute - would be most pleased to help you with not only your bellows, but any musical instrument you have that might require attention. Feel free to see him if you need help. If you are curious about how a bellows works, feel free to examine the one lying here - Flute would not mind.

He might mind, however, if you were to enter his apartment above his workshop. His apartment is his private space.
