Beware when you use this item, caution is required, and Grimm & Co cannot be held responsible for any magical disasters or the sense of impending doom.
Note for Mortals:
Polished halves of ammonite fossils. Colour and size selected at random per order. An ideal fossil to add to a collection and display on a shelf.
