"And the fancy kind of paper, too. You wanna make a statement." He assumes certain kinds of parchment were fancier/more expensive than others, at any rate.

Prompto snorts at his description. "Ah, the worming was more done by me than anything." Noctis had just been nice to him once, but the prince usually kept to himself at school for obvious reasons. Too many would use him to just get an in with the king, or because they wanted to brag about being friends with a prince. That sort of thing. "Not because he was a prince, though." Which is what most probably assumed, but he didn't care. Noct knew Prompto liked him for the person he was, and that's all he cares about.
