Unused. Approximately 17.4cm x 343cm. It will be folded to fit and shipped via Yu-Packet Post, so two sheets cannot be shipped together. They will be shipped individually. If there are many items, such as 5 or 6, we will consider using Takkyubin (home delivery service), but the shipping cost will increase significantly, so the discount will be small... Due to the system, we cannot reply to requests for combined purchases, so please contact us via comments. Please note that items may be compressed for shipping. *Please read the profile and understand before purchasing.
