This 12" steel rod is multi-faceted all along its length, with a smooth spinning disk on each end that extends just barely above the rods faceted surface. There is also a magical rune on each end of the rod.
If you use an action to press one of the magical runes you can roll the rod over a piece of parchment, sheet of paper in a book, scroll, or other similar surface. In doing so, you cause any writing, illustrations, or markings that the rod rolls over to be magically stored within the rod. If the rod has any writing currently stored, the rune used to activate the storing function glows softly, and you can see fragments and pieces of the stored writing faintly moving along the facets of the rod.
Stored writing remains in the rod until transferred or the rod is used again to store any new writing, thus causing any previously stored writing to disappear from its magical memory. Once stored, this writing can then be transferred to another scroll, parchment, or similar surface by using an action to press the rune on the other end of the rod and rolling the rod over the new paper surface. Once stored writing has been transferred, the rod's memory is empty and the previously glowing rune ceases to glow.
If the new surface that writing is being transferred to is not large enough for for what is stored within the rod, any such writing that cannot fit onto it is lost. In addition, the writing surface that is being read from or transferred to does need to be reasonably flat in order for the rod to function.
