If you want to completely immerse yourself in the Halloween spirit, then you need the Marker of the Beast. These come in a set of two and are perfect for spreading Halloween cheer and fear.
The Marker of the Beast is labeled as such and features '666' down its side. Only 1,000 sets of these pens will be made, so you need to act fast if you want to get your hands on these. Check them out in the gallery above.
