This is a 35mm twin-lens reflex camera kit. When assembled, it becomes a twin-lens reflex camera that uses 35mm film. It was originally included as a supplement to the magazine "Otona no Kagaku" (Adult Science). I've already gotten rid of the magazine itself. The assembly instructions were included in the magazine, so they are not included. I think you can take atmospheric photos with soft exposure. I've been wanting to use it myself and have been keeping it, but I haven't been able to take action, so I'd like to pass it on to someone who will enjoy using it. The kit is unopened, so I believe there are no damages or missing parts. - Model Name: 35mm Twin-Lens Reflex Camera - Functions: Film counter, shutter, wind knob, tripod socket - Features: Retro design, compact size, photography experience - Size: Approximately 117mm x 110mm x 180mm Thank you for looking.
