Contact me via my contact page or my Instagram. You will be responsible for shipping the item back to me. Once it is received(undamaged) I can issue a refund.
Please let me know if your sticker was damaged during transport by contacting me via this site or my Instagram and I will handle it on a case by case basis. I will not be able to do any exchanges on most stickers. Since they are a limited run item, once they have run out I do not have any more to give in exchange.
