I believe this is a SANWA Mycro film camera made by Sanwa Shokai. The lid for inserting the film comes off when opened. Please be careful when opening and closing the lid. Please also check the images for other details. I was unable to confirm its operation. I am selling it as a junk item, so perhaps you could use it for your collection or for parts. Since the details are unknown, please confirm and make your own judgment. Condition: Possible stains, age-related deterioration, and signs of use. Thank you for looking. #SANWA Mycro #MicroCamera #MiniCamera #FilmCamera #Crafts
