This Northwind, black leather wrapped, wood case, is designed to fit a C flute with a B footjoint (usually A440 flutes). If you are uncertain, please provide accurate length measurements of head, body, and foot (i.e. body 14 12/16 inches, foot 6 8/16 inches, head 8 10/16 inches), and we will check the proper case size for you. The interior block must be permanently placed with a small amount of all purpose glue. This will allow you to customize the fit of your new case. Available interior velvet colors may vary.
