How about a handy eraser that you can put in your pencil pouch? This great quality eraser is retractable so you can keep it neat and clean and because it has genealogy stamped on it, surely your family will leave it alone! It also has a clip in case you want to put it in your shirt pocket. It says "Genealogists never make mistakes!" and will surely be a hit at the library, archive or court house where often only pencils are allowed. Makes a great gift too! Measurements: 4" long x 1/2" wide.
