The two hourglass pens in ebony and ivory (black and white)are PANACHE pens, and are probably the most recognizable pens to penmakers and collectors. While maybe not the best for everyday writing, one cannot deny that they are conversation pieces (and the pens work just fine).  I guarantee that if you have these on your desk or on the coffee table, people will start asking questions. 
 
The pen in front, on its side horizontally is the ELECTRA in gold. This pen comes with a gold top, as depicted here, or a silver top. The tops are intricately scalloped, and the fitings on these pens are very impressive. People absolutely love the delicate luxury of the way it feels in hand, and in the way you just feel special when writing with it.
