It's a possibility that's for sure. I got an email back about it, but seems they don't know either. He did mention about putting it one, but I believe you already know this and it's purely that it did indeed dry out.
"The clear transfer tape is the sticky one not the white paper. The clear sheet is what you pull of with the decal on it to apply the decal. They are probably not doing that and keeping the decal on the white sheet which is the outside of the decal."
I'm going to email them back, but would you mind sending me a picture of it as it is currently and more information on how you proceed after you opened the envelope up? I want to make sure that we get this worked out if at all possible. If you could do that, please send it over to my email at XQstudios[@]gmail.com.
Thanks!
