Northwind, black leather wrapped, wood case, with blue velvet interior, is designed to fit a C flute with a C footjoint (usually A440 flutes). Flutes with a body longer than 14 6/16 inches, may require this extra long case. If you are uncertain, please provide accurate length measurements of head, body, and foot (i.e. body 14 6/16 inches, foot 5 4/16 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.
