## Long description

Advantages
The Curidas Prism Crystal offers stable ink delivery and an extra-fine nib that produces crisp, narrow strokes suitable for technical notes and delicate handwriting.

Key specifications
Nib size: Extra-Fine (EF) for narrow line width
Body: Transparent prism-style barrel revealing internal parts
Filling options: Refillable with bottled ink or compatible disposable cartridges
Manufacturer: Platinum
Intended use: Precision handwriting, sketching and technical notes
How to use
Prepare the pen by installing a compatible ink cartridge or by using a converter to fill from bottled ink, following the converter manufacturer’s instructions. Hold the pen at a natural writing angle and apply light, consistent pressure — the extra-fine nib is designed for minimal pressure and controlled ink flow. For best results, write on smooth, fountain-pen-friendly paper to avoid feathering or bleed-through. Clean the nib and feed periodically by flushing with clean water when changing ink colors or if flow becomes uneven.
Usage recommendations
Use high-quality fountain pen ink and smooth, medium-weight paper to preserve nib performance and obtain the clearest extra-fine lines. Regular cleaning and correct storage with the cap secured will extend the pen’s service life and maintain consistent ink flow.
