Iron Core


This die is iron on the inside and can be detected/influenced by a magnet.

Options available :
★ choose white with black spots or red with white spots


This die contains a 16mm iron core hidden inside the 18mm die. The core is made from iron particles set in resin and moulded into a shape which conforms to the exterior shape of the die, therefore the outer skin of the die is a uniform 1mm thickness.

The iron is attracted to a magnet – strongly, but not as strongly as if the core were solid iron rather than resin/iron mix. Similarly, the die doesn’t weigh as heavily as it would if the core were solid iron, therefore it can be handled without arousing suspicion. Detectable/interactable by a magnet through several millimetres of wood.

This die is often used in conjunction with a magnetic PK ring for detection routines such as the Kurotsuke effect, or with a chop cup for a vanish routine.
