Thank you for visiting the product page (⁎ᴗ͈ˬᴗ͈⁎) Regarding the bonus item from the official store, I'm offering it for sale because I received a duplicate. I have opened the package once to check the contents. Please refrain from purchasing if you are concerned about the item's condition, as it has been stored by an amateur. I will return the item to its original silver packaging and ship it with measures to prevent water damage. I hope to pass this on to someone who needs it (❁ᴗ͈ˬᴗ͈) Thank you very much.
