Your Streamline pen has a ‘Cross’ type refill; the Sierra/Bolt Action have ‘Parker’ type; the JR Rollerball Pen has a Schmidt refill, and the JR Fountain Pen has a standard cartridge.

These are available to buy on the website.

To replace the Sierra refill you twist the wood part (lower) in a clockwise direction and pull apart (do NOT unscrew it anticlockwise), then unscrew the lower silver part above the nib section. The Streamline pulls apart in the middle; the Bolt Action you screw off the copper nib end, the JR Rollerball you unscrew at the top (watch out for the spring!), and the Fountain Pen you screw off above the nib.

If you need help replacing the refill let us know by email –
