The pen is wonderful- a very smooth writer! Emy from Pen Venture wrote a nice note- I really appreciate this thoughtful touch. The pen came fast, writes great, and the service is excellent-what more could I ask for? Thank you.

This has quickly become one of my favorite pens. The aluminum body feels incredibly solid without being overly heavy, and the machining is excellent. The vacuum filling system is satisfying to use and holds a huge amount of ink. I currently have it filled with Diamine Athol Violet, and the combination has been fantastic. The fine nib is smooth, wet, and really brings out the richness of the ink. If you appreciate a well-built pen with a unique industrial design, the Gravitas Vac 2.0 is an outstanding value.
