Seishin no Kabushiki look like round, black poles. They're approximately three feet in length and half a centimeter in diameter, although they're far more durable than one might expect. A coloured strip runs down on either side of the pole, and it's colour determines how much reiatsu is left within the tool. If the strip is blue, it is more than half full. If it's yellow, it's half full, and if it's red, it's only a quarter-full.
