A cello case is a protective container designed to hold and transport a cello, a string instrument played with a bow. These cases are typically made from durable materials like fiberglass, wood, or carbon fiber, providing a safe environment for the instrument. They often feature padding inside to prevent damage and may include compartments for accessories such as bows and rosin. Most cello cases come with handles and shoulder straps for easy carrying. Some models are lightweight for convenience, while others offer extra protection for professional musicians who travel frequently. The design ensures that the cello remains secure and intact during transport.
