Hetman Light Rotor Oil 11 for French Horn

I originally purchased this as a backup, but decided to use a different oil, so it has been stored unused.
The outer box is crushed, but the oil is full.

I would appreciate your understanding that this is a used item and has been inspected by an amateur.
Please note that returns are not accepted.
Thank you for your understanding.
