Although it is new and unused, I do not know the year of manufacture. It was kept carefully for many years by a relative who loves Doraemon. I am also selling another of the same item. It has not been taken out of the outer box and is in the same condition as when it was purchased, but the sides are open. Returns and complaints will not be accepted in the event of a defect. Please understand this. Please purchase only if you understand. For those who love Doraemon, or for children who love Doraemon, how about a battery-free, easy-to-use music box as a gift?
