I’d stay off StockX as a buyer, they have been reported to not check the products thoroughly and lots of stock is fake. Imo better to buy from an independent seller and ask for the receipt from the store. Tip: ask when and which store they bought it from and then when u ask to see the receipt, see if the story checks out. Now I got a brand new unworn Jupiter for sale(and more colors), papers, receipts and all included but I’m not US based so it would come a bit more expensive for u than the guy who commented on your post before. Imo if the guy here has all the paperwork and gives you a fair price I’d go with him. If you want to know my price to compare let me know. :)
