'Escura' is the film/camera branding used by a Hong Kong-based company called 'Carbon'. They offer an instax camera as well as a Hasselblad back and various 'designer' 35mm (reusable?) disposables.
their instant camera is interesting--instax mini, but no battery? I imagine hand crank to push the film through the rollers, but what about exposure? The specs show a limited aperture range (ƒ12-ƒ16) but nothing on shutter.
