This is a glass bottle shaped like Felix Felicis, the liquid luck from Harry Potter. The chain is approximately 80cm long. It has a sticker that says "Felix Felicis" in a font similar to the movie. The resin inside has hardened, so there is no need to worry about leaks. This can be used as a prop for Harry Potter cosplay. * The actual resin pattern and amount may differ slightly from the photos. * There may be distortions from the molding process at the opening of the glass. * As this is an overseas product, please be aware that there may be color variations, burrs, chips, or small scratches.
