Meet the Nemosine Singularity in (from left to right) green, aqua blue, pink, white (not to be confused with ivory), magenta and blue marble. All pens are appointed with chrome trim, clip and cap band. The front section is black with the German-made, stainless steel nib attached. As with any of the Nemosine pens, a converter and (6) ink cartridges are included with the purchase of the pen.
You may be looking at this picture and thinking, "wait a second, the Blue Marble is bigger than the other Singularity pens?" Your eyes do not deceive you. It looks bigger posted because of the thickness of the acrylic used to make the marbled barrel and cap. The thicker cap doesn't allow for as deep of a posting than the solid-color Singularities. This could also be the reason that the Blue Marble is just a tad bit more expensive than the other Singularity pens.
With the wide array of colors and nib sizes (Extra-fine, Fine, Medium, Broad, 0.6mm stub, 0.8mm stub), it is easy to see why Nemosine fountain pens can be addictive to the pen enthusiast. They are affordable enough to own several for different purposes and situations where you would find yourself needing a fountain pen. Example - keeping a Nemosine in your desk drawer at work, one at home and one on your person (briefcase, purse or pen case). Also, if you love fountain pen inks as much as I do, you may have one pen dedicated to a particular type of ink. When you feel in a blue mood, take out the aqua blue or the blueberry and write away in some Diamine Aqua Blue. The combinations and possibilities are endless!
