I have sadly lost my Ultra Pro Mermaid Deck box. It has THIS sticker on the side of it.
It had very sentimental dice in it, and other GenCon dice as well. The cards were a Commander Jinnie Fay deck.
IF FOUND - $50 REWARD
Good luck on your search. You have my sypathies. I never take anything on vacation I don't want to lose (signed books, sentimental dice, etc).
Again, good luck. I hope you get your dice back.
Did you try the ICC lost and found? They might have it.
