These Talking Tomica are not often available, and these are also unopened. I believe it's rare to find a complete set of 6. I stored them in a dark place immediately after purchase. They are supposed to talk, but I haven't confirmed the function as they are unopened. It seems that LR44 test batteries are included on the back, and there is a possibility of battery leakage due to long-term storage. Please purchase only if you understand the above points.
