Benesse Kodomo Challenge, 2nd Grade, Multiplication Table & Clock, Light Blue This is the main unit only. There is no box or instruction manual. I received this a few years ago and carried it around with me for a few months when going out. You can learn it enjoyably because it helps you memorize through songs♪ Operation confirmed. Thank you.
