Uni-ball Jetstream Prime Twist Type 0.5mm -Dark Olive [SXK-3300-05.18]

The nib side half is made with brass, and the upper half is made with stainless steel, so the centre of gravity is on the nib side which makes it well-balanced and easy to write with.

The pen has a luxurious design that tapers gently towards the tip and an elegant shape that can only be achieved with a rotary feed. 

Pre-Installed Ink Colour: Black

Suitable refills are SXR-600-05
