Below is from the Lizell catalog from 1999.  (Lizell was a Levengers-type store in the Philadelphia region.)  I got a handful of these in a variety of colors and used them every day as well.  These have a great fun factor too as they retract either by using the push button or by pressing the top of the clip.  Addictive!  (I don’t remember what will refills fit these but I had found something not too long ago.)

$9  each (plus shipping) for the yellow, blue or white.  $12 for the black just because there’s only one left.  I will discount for multiple pens.
