Overview

Platinum’s Curidas Abyss Blue fountain pen shows its retractable mechanism through translucent blue resin, making its inner workings part of the design.

The mechanism is part of what you see through the translucent PMMA resin. Curidas takes its name from kuridasu, the Japanese term for extending the writing tip, and “curiosity.” Watching the parts move brings that idea to life. Platinum’s Knock introduced the retractable design in 1965, and Curidas returned to the idea in 2020.

Press the rear button to extend the stainless steel nib, then press again to retract it. At rest, the nib sits inside the Nib Pocket, where a lid and soft elastomer seal limit moisture loss in the small chamber.

Use Platinum SPSQ-400 or SPN-100A cartridges, or fill from a bottle with Converter 700A or 500A, sold separately. One blue-black cartridge is included. The box also contains a tool for attaching or removing the chrome-plated spring-steel clip.

Made in Japan, the pen measures 153 mm in length and 13.8 mm in maximum diameter, and weighs 24.0 g.

Questions & Answers

How does Curidas work without a separate cap?

Press the rear button to extend the nib and again to retract it. The retracted nib sits inside the Nib Pocket, whose lid and soft elastomer seal limit moisture loss.

Which cartridges and converters fit?

Platinum SPSQ-400 and SPN-100A cartridges are compatible. For bottled ink, use Converter 700A or 500A, sold separately.

Can I remove the clip?

Yes. The included tool lets you attach or remove the chrome-plated spring-steel clip. One blue-black cartridge is also supplied.

What does Curidas mean?

It combines kuridasu, a Japanese term for extending the writing tip, with “curiosity.” The translucent body lets you watch the retractable mechanism at work.
