A solid writer with a beautiful swirl resin design, this is a piston filler from Nahvalur (previously called Narwhal) pens. I have too many Nahvalur pens (all pretty), so I'm selling this to trim my collection down. I used this only twice.

Here's the formal description from the Nahvalur site: 

Introducing our new color Cichlid Purple for our Schuykill Collection! As their name suggests, we drew inspiration from these widely popular and beautiful freshwater fish and created this mesmerizing pen in our Schuylkill collection. Nahvalur's Schuylkill Cichlid Purple fountain pen offers a smooth, effortless writing experience. Featuring exclusive resin material, a reliable piston fill mechanism, and a unique ink window, you can easily gauge your ink levels while enjoying its lightweight design. Crafted with the highest attention to detail, this pen is the perfect choice for a writing pleasure.
