Please feel free to inquire about your desired price. This is a Japan Post cash envelope (for registered mail). It is marked as issued by the Ministry of Posts and Telecommunications. It includes an inner envelope (double envelope). It is a carbon copy type, but still usable. You can remove the carbon copy part and attach a label to send it. Although it is new and unused, it has been stored at home, so there is some age-related wear and tear, such as creases. Please refrain from purchasing if you are sensitive to such issues. Please check the condition in the photos. Showa retro, collection item.
