Abstract: A key chain note holder includes a fiat housing (10) having a transparent side (17) and an opaque side (18). An elongated slot (12) extends into the housing between the sides for slidably receiving a note card (13) having a white, reusable writing surface (13A), and a brightly colored opposite surface (13B). The housing also includes a hollow shaft (20) extending thereinto for slidably receiving an erasable marking pen (21), and another hole (14) for receiving a key ring (15) for carrying one or more keys (16). The note card and pen can be removed from the housing for note taking, and replaced therein for convenient storage when done. The note card can be reinserted into the slot with the writing surface facing the transparent side of the housing, so that the notes are conveniently visible; the housing also protects them from accidental erasure.
