Detective Conan Magic File 2: Kudou Shinichi - The Case of the Mysterious Wall and the Black Lab

Magic File 2 was sold at select retailers (7-11 branded equivalents) in Japan, along with PPV episodes of the show (episodes released long before, such as the NY case). The first disc housed the Movie 12 Side-Story OVA, which features Kudou Shinichi and details a bit of the backstory from the upcoming movie. The second disc was the one with the PPV episodes.
