[About the product] All items, regardless of whether they are new or used, have been stored at home for a long time. I inspect the items, but I am a private seller, so there may be oversights. Please refrain from purchasing if you are looking for products like those sold in stores or require quality assurance. If you have any questions or requests regarding shipping, please be sure to ask before purchasing. (Answers to frequently asked questions are listed in my profile, so please read it first if possible.) Returns and refunds are not accepted after shipping.
