Messenger's Mirror

Sending Mirror. This mirror is connected to another of the same kind. You can speak a command word to activate the mirrors. While the mirrors are active, their reflections are swapped. Each mirror shows the view from the other. The mirrors cannot function if they are on different planes of existence. You can speak the command word again to deactivate the effect and return the reflections to normal. Regardless of whether the mirrors are active, you can pass one object that fits in a 3ft.-cube through them, causing it to appear out of the other mirror. After an object has been passed through, you cannot send another object through the mirrors for 24 hours.
