10 random rolls of film. On occasion we roll the wrong film, wrong quantity, ect, we are human, it happens. These films get put on a shelf. Well the shelf is getting full! so 10 random rolls for $75 while supplies last. sorry you cannot choose the patterns you receive. some will be 100cm some will be 50cm. this is a great price for the people who are learning, building displays, or have personal projects.
