Yashicaflex Twin Lens Camera Yashica Flex [Operation Check Details] Operation not confirmed. - I only confirmed the shutter operation, which made a "shutter" sound a couple of times. Other operations are unconfirmed. Since operations other than the shutter have not been confirmed, this is a current condition item. Please purchase only if you understand this. *Shutter confirmation was a short operation check of 2-3 times. This is a junk item with unconfirmed operation. Please consider this before purchasing.
