They leak so much the pressure can't build up. These things are horrible.

The fujifilm instax mini instant film twin pack captures the essence of what makes instant photography so captivating. The film delivers instant gratification, making every photo-taking experience exciting.

Will be seeking a refund. But that is not what you're purchasing. Replacement product was also expired.

More than half of the photos are not developed. Bought 2 double packs and all 4 cartridges had horrible picture quality.
