SKYLRK Justin Bieber POP UP HOODIE XL New This is authentic, of course. As a general rule, I will not provide copies of receipts, etc., as it is troublesome. If you are not satisfied, you are welcome to have it authenticated yourself. I will block questions asking for confirmation. You do not need to purchase if you are not satisfied. To prevent item substitution during shipping, I may take a "video." Thank you.
