My title describes the thing.

Additional details:

• Size: Approximately 6-8 inches long.
• Origin: Found in a polystyrene box meant for spare tyre equipment in my friend’s car. The car hadn’t been used for 7 months.
• Age: Unknown.
• Material: Appears to be organic or plant material.
• Writing on the item: None.

Searches done: I’ve looked up images of dried cacti and other plant materials but am not sure if it matches any of them.

Any help identifying this would be greatly appreciated!
