Edible Lip Gloss

Edible lip gloss is a product that was given to Sophie on midterms by Biana. Like Keefe's, Marella's, and other prodigies' who gave sophie gifts, this was not a disappointment, as Fitz's present was by itself. It is unknown if Sophie is using it in the later books, though quite a few times narration describes Sophie putting on lip gloss, that could possibly be this type from Biana.
