Thank you for viewing. This is a used YASHICA CS-10 flash strobe. The internal condition of the main unit is unknown as it has not been disassembled. Accessories: Case Batteries: None This is a used item that has been in someone's possession. Please refrain from purchasing if you are nervous or seeking perfection. My grandfather, who used to work at a camera store, kept it carefully stored in a dehumidified storage unit.
