These two have an embossed five point star on the upper side. The star is visible on the right LRI, in the direct center. The star embossing is always found in the same location. It seems that all of the star LRIs that I've seen and owned are from the same mold! The LRI on the left has the star turned to the back, so that the wonderful graphite trail would be visible. This one is the normal color for the Star LRI: light blue aqua. The LRI on the right has a deeper aqua color.
