Also to be clear, the judges are fine with "fluff", but only so long as it adds to the item. "crafted from sterling silver" is good fluff "also, this will prevent you from losing your keys" is fluff the judges don't really like.
What the judges hate, however, is backstory. Wondrous items are not unique. They are also not based on unique items or historical events. And most importantly, they never reference characters (unless the character is an existing Golarion pantheon god - they one only get a flag, instead of a reject).
See, I'm going to disagree.
Sometimes that little bit of fluff is what makes it 'Superstar'.
Ohhh boy interesting..
