Problem with gem store skin I bought
I doubt they will give a refund since the description states it is a one time use per piece.
For a price and some time investment, you can. You have to transmute the skinned item onto a low white item. Then put that in the bank and withdraw it on the alt. The alt can then transmute it back onto a stat item. You can only have one of it at a time, though.
If you want to try for a refund you can contact support with the tab at the top of the page then go to ‘ask a question’. They are the only people who can answer your question and give you a refund if the answer is yes.
