Benesse Kodomo Challenge DVD Set, 15 Discs Total - Number of discs: 15 - Series Name: Kodomo Challenge Petit This is a set of 15 discs, including trial versions. The discs from January onwards are from 2013. They have been shown to children, so there are scratches, but they play without problems. Since I haven't confirmed playback on all of them, I would appreciate it if you could understand. Comes with a case, so you can carry them around easily. Thank you for looking.
