I will try to respond to comments as quickly as possible, but depending on my work situation, my response may be delayed. I will respond even if it's late, so if you have any questions, please feel free to ask in the comments before purchasing. Instant purchase OK Please refrain from aggressive price negotiations. Let's have a pleasant transaction. ☆Please read before purchasing☆ This item is stored at home. I will check the item when listing and shipping, but as I am an amateur, I may overlook something. If you are concerned about minor details, please refrain from purchasing. As I have irregular days off, I have set the shipping time to 4-7 days. Shipping is planned via Mercari delivery, but for convenience, there is a possibility of changing from Yu-Yu Mercari delivery to Raku-Raku Mercari delivery without notice. Regarding returns, if the item is significantly different from the photos, I will accept returns, but in that case, the buyer will be responsible for the return shipping costs. (I have records of photos and serial numbers other than those disclosed) If you request a dedicated listing in the comments, I will accommodate you as much as possible, but currently, the Mercari system allows other users to purchase even if it is a dedicated listing. I am very sorry, but please understand that I will proceed with the transaction with the person who purchases first. Please consider purchasing after understanding the above. Thank you.
