Thank you for viewing. ☆Please read before purchasing☆ Please consider purchasing after understanding the following. I will try to respond to comments as quickly as possible, but replies may be delayed depending on my work situation. I will respond even if there is a delay, so please feel free to ask any questions before purchasing. Instant purchase OK. Please refrain from aggressive price negotiations. I appreciate your cooperation in making our transaction a pleasant one. ☆Please read before purchasing☆ This item has been stored at home. I will check the item when listing and shipping, but as I am not a professional, I may miss 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 will be 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.
