The body is durable, yet light, making it comfortable for long writing sessions. On social media you can see some body break issues. Based on our firsthand experience, we havent had any broke problems. Even the first model that we have for 7 years.

Nib

The VAC 700R IRIS comes with a #6 JoWo nib, #6 nib makes this pen our favorite in TWSBI line. (ECO and 580 models have number #5 nib).The stainless steel nib that glides smoothly on paper, offering a consistent ink flow. The nib is iridescent, matching the trim for a cohesive look. Nib unit is screw-on, so easily can be swapped with replacement nibs or any JoWo # nib.

Cap

The cap of this pen is screw-on with an inner cap to prevent the nib from drying out. It features an iridescent clip that complements the overall design of the pen.

Filling System

One of the key features of this pen is its vacuum filling system, like Pilot 823. We know this is a love-hate filling system. The vacuum filling allows for a larger ink capacity and a fun, unique way to refill the pen. If you haven't used any vacuum filler pen, you have to do some practice first.
