Operation confirmed. Please be sure to read the profile before purchasing. Please understand that delivery may take time with regular mail. There is no regular mail delivery on weekends and holidays. We are troubled by many inquiries from people who are unaware of this. If there are days when we cannot ship, we will note them next to our name. Regarding returns and exchanges, we will follow Mercari's rules, but for the sake of preventing trouble, a video of the opening is required. Please refrain from purchasing if you are concerned about minor scratches that do not appear in the photos, as they are stored by an amateur. We will discount 100 yen per item from the second item for simultaneous purchases with other products (if the shipping size does not change). Please feel free to contact us with a comment.
