Polyjuice Potion Bottle by The Potions Mistress.  The label features an illustration of Severus Snape.  “Snape’s Handwriting” on the tag was created from the handwriting in the copy of Advance Potion Making that was featured in “The Half-Blood Prince” film. Each letter was meticulously copied by hand and then rendered into a font. The quote on the tag comes from the first speech Snape gives to the students about the beauty of potion making.
