Description
Magneto’s cap closes on a magnet instead of a thread, so it clicks shut in one movement and lifts off without a twist.
Pure copper darkens to a deep, even brown as it meets the air and your hand. Polish it back to bright, or let it keep the record.

Where is the Magneto made?
The Magneto is machined from solid copper and finished by hand at the STEX workshop in India. Its makers spent more than twenty years in the copper trade before making their first pen.
How big and heavy is the Magneto?
It measures 140 mm capped and 171 mm with the cap posted. It weighs 51.25 g without ink. The drawing on this page shows it to scale beside a bank card.
Can I post the cap?
Yes. Fit the cap on the end of the barrel and the Magneto measures 171 mm, a longer writing length.
Which nib does it use?
A German Schmidt steel nib (Schmidt M), with a Schmidt converter for bottled ink. Medium is standard; Fine and Bold are also available. Schmidt nibs are smooth, reliable and easy to replace.
Which ink does it take?
Any bottled fountain pen ink, using the Schmidt converter, or a standard international cartridge when you are travelling.
How do I care for the copper?
Wipe it with a soft cloth and let the patina grow. To bring back the shine, polish gently with a little lemon and salt or a copper cleaner, then rinse and dry. Keep cleaners away from the nib and grip.
How do I look after it?
Keep it capped when you are not writing, use fountain pen ink only, and flush the nib section with clean water every few weeks or whenever you change ink.
Which currency will I pay in?

The copper will remember you.
Raw copper darkens with every day of use. Drag the slider to see how this pen might look after a year in your pocket.

Fresh from the lathe: bright, rosy copper with a mirror sheen. Every fingerprint shows, and that is how it begins.
