A pinch of that, a snippet of this. Every wizard needs a cauldron to brew their potions. Carry yours with you with this Harry Potter Potion Cauldron Charm on a silver plated charm bail. This charm has been created using the official style guide from Warner Bros. It is approx 16 x 18mm. This charm comes on the official Harry Potter branded card packaging and shows the Warner Bros logo on the reverse. This charm is compatible with our other Harry Potter slider charms, necklaces and bracelets (sold separately). Cauldron does not actually work.
