FAQs
What type of ink does the Platinum Biso use?
It uses standard Platinum ink cartridges or the compatible Platinum proprietary ink converter.
Can I use bottled ink with this pen?
Yes, if you equip the pen with a Platinum proprietary ink converter, you can use any fountain-pen-safe bottled ink.
How should I store the pen to prevent drying?
Always ensure the retractable cap mechanism is fully engaged when not writing to prevent the ink from evaporating at the nib.
Is the nib size interchangeable?
The nib is integrated into the design. We recommend against attempting to remove or swap the nib to avoid damaging the internal mechanics.
How do I maintain the pearlescent finish?
Wipe the pen periodically with a soft, lint-free microfiber cloth to remove oils and debris that can dull the finish.
Troubleshooting
Inconsistent ink flow
Flush the nib with room-temperature water and ensure the converter is fully seated.
Retractable cap feels stiff
Gently clean any dried ink residue from the cap opening using a soft, damp cloth.

Setup, Compatibility & Care
To begin using your Platinum Biso, insert a compatible Platinum ink cartridge or a proprietary converter into the nib section until it clicks securely. When not in use, ensure the retractable mechanism is fully closed to seal the nib against air exposure. To clean the pen, flush the nib assembly with room-temperature distilled water every few weeks or whenever you switch ink colors. Avoid using harsh chemical cleaners or abrasive materials, as these can damage the pearlescent finish of the resin body. Store the pen in a dedicated case when traveling to protect the gold trim and exterior.
