Thank you for viewing. This is a supplementary item for second grade students, a multiplication table song band. It hasn't been used much, so I think it's in good condition, but the batteries are still inside. You can use it right away, but I don't know how much battery life is left. They might run out soon. Multiplication table songs sung by Korisho Timer Stopwatch Multiplication, addition, and subtraction learning It does not have a clock function. There is no box or instruction manual. Only the watch shown in the photos. Thank you for your interest. Thank you for viewing.
