This is a new, unopened set of [Arabida] and [X39]. Expiration dates: Arabida: [2027/02] or later X39: [2026/12] or later Two instruction manuals included. Will be packaged in an aluminum zip bag. For those who wish, I can create a dedicated listing if you leave a comment. Regarding shipping during the summer, for those who prefer Takkyubin Compact for quality preservation (e.g., unable to receive from the post during the day, away from home), I will create a dedicated listing with an additional shipping fee of +400 yen. Thank you.
