Moons of Jupiter fountain pen : Sinope and Thelxinoë

We have added two purple/violet/mauve pens to our The Moons of Jupiter series: Thelxinoë (with the darker moons) and Sinope (lighter, with the semi-translucent grip section). Thelxinoë’s (pronounced thel-ZIN-oh-ee’s) moons are so dark as to almost invisible in normal indoor light, but in brighter light her purple sparkley moons are both elegant and subtle.

Sinope’s (pronounced sih-nOH-pee’s) moons are a lighter, ever so slightly translucent grey-violet, with a section that has streaks of shimmer that shift from sapphire to mauve.
