This is an authentic product. I checked the contents after taking it out of the shipping box, but the product box is unopened. It has been stored in the shipping box the whole time, so the condition inside is good. Please comment before purchasing. I will ship the item in the original shipping box. If you have another preferred shipping method, please let me know before purchasing. To prevent product substitution, returns are generally not accepted. Because the product is unopened, I am not responsible for initial defects. In the unlikely event that the product significantly differs from the description, please contact me via the transaction message with details before rating the transaction. Please note that returns will only be accepted if the following conditions are met: * You can provide an unedited video clearly showing the product from opening to packaging. * You can prove that the returned product is in the exact same condition as when it was shipped. As a measure to prevent product substitution, I will take detailed photos and videos before shipping the product, and I will record the entire packaging process.
