I've decided to sell these as a set because they weren't selling well individually. I opened them to check the contents, but they are unused. This is a keychain from the 2023 Valentine's Day version and a sticker that was included in the Oricchu sold in 2022. Price reduced! If you purchase both, it's 700 yen (including shipping). You can also purchase either one individually, so please let me know in the comments. The shipping method is standard mail, but if you prefer Mercari shipping, please let me know in the comments.
