I don't have a sewing machine that can be used for long-term storage items, so I don't know if it works properly. The bobbin case has rust. There are two heights. The shallow one is Clover I-2. The deep one is Clover, with no model number, and one marked only J-H3. 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 this listing suddenly. I will pack it as compactly as possible. I may change the shipping method between Kuroneko Yamato and Japan Post.
