These are items for long-term storage. I don't know if they will work when connected. There are two items with the SONY mark. I am careful about future storage, but there is a smoker in my home. Please refrain from purchasing if you are concerned about details regarding the product, packaging, or shipping. I may delete the listing suddenly. I will pack as compactly as possible. I may change the shipping method between Kuroneko Yamato and Japan Post.
