Although unopened, the vinyl has become dusty due to long-term storage. Also, I do not know about the deterioration of the contents. Please consider purchasing only if you understand the condition. ● Hajime Mutsuki ● Haru Yayoi ● Shun Shimotsuki ● Kai Fuzuki This is a set of 4. If purchased individually, they will be 1777 yen each due to their thickness. Packaging will be bubble wrap and measures to prevent water damage. I plan to ship via Rakuraku Mercari's Takkyubin Compact or Takkyubin. Other transaction details are listed in my profile, so please check them. After that, if you have no questions or problems, please purchase as is. ※ This is separate from the Haru + Gravi set I have.
