Snape could be behind the Harry Potter Potion N. 113 Keychain or possible Slughorn, no matter at least with this half empty or half full bottle of potion, you will have a bit of magic with you everywhere you go. The liquid kind of looks amberish, but in all actuality, it is not even a liquid. Since this potion was taken illegally by those ThinkGeek guys no one knows exactly what the potion might do. You may find that it will turn your enemies into toads or it might just put warts on your face. If you are not brave enough to discover the magic, at least it will help you carry your keys.
