Tired the iron method with low heat. On both the outside and inside of the number at it was a no go. It looks like the small amount of adhesive that was used to lay the number on is wrinkled and it's causing the number to have the indentation. I'm calling TTS tomorrow. I hope that there are not any issues with stripping the number. I wouldn't normally worry so much about the jersey, but it's not like this one is popular enough , in new condition, where I could just get another. Makes me really paranoid about it.
