This item is new and unused, but the manufacturing year is unknown. It was carefully stored for many years by a relative who loves Doraemon. I am also selling a Dorami-chan timer, which is the same product. It has been kept in its original packaging since purchase, but one part of the outer box is open. Returns and claims are not accepted in case of defects. Please understand this. Please purchase only if you agree to these terms. This timer is perfect for Doraemon fans, or for children who love Doraemon, to time things like a "3-minute" timer. Batteries are sold separately.
