This is the touch pen for the "AEON KIDS First English Lesson Picture Book." As shown in the photos, the power has been confirmed. When powered on, the light turns on and sound is produced (volume buttons also confirmed). The book was heavily scribbled on and disposed of, so this is the touch pen only. The batteries are included, but the remaining life is unknown. It has been disinfected with alcohol and cleaned, but there is some dirt on the top, so please refrain from purchasing if you are concerned. *Operation has been confirmed, but please check the operation yourself before rating upon receipt.*
