This quality Parker style pen refill fits many of our bespoke pens including: Sierra pens (click and twist style), stratus pens, executive pens.
This is a quality pen refill and the blue ink flows consistently for a smooth writing experience.
This pen refill is easy to replace:
For the sierra twist and executive, simply pull gently on the lower part of your pen where the timber meets the metal fitting. It will slide apart using a small amount of pressure.
For a sierra click style pen, simply unscrew the pen fittings by unscrewing where the timber meets the black front/nib end of the pen. It should unscrew easily and does not need to be forced.
