Smooth flow every time
I was worried about scratchiness with such a fine tip, but the flow is surprisingly smooth. It glides across the paper effortlessly. The ink density is perfect for scanning artwork later.

Perfect for intricate details
I use this pen primarily for manga inking and the 0.05mm line is incredibly consistent. The oil-based ink dries instantly and doesn't bleed through my Bristol board. Highly recommended for professionals.

Great pen, requires care
The line quality is superb, probably the best 0.05mm I have used. Just remember to cap it immediately after use since it is oil-based; if left open, the tip can dry out quickly.

True waterproof quality
Tested this with watercolors over the top and the lines did not smudge at all. The jade green body looks elegant on my desk too. It feels balanced and comfortable during long drawing sessions.

Excellent for technical drafting
As an architect, I need precise lines for my initial sketches. This Platinum fineliner delivers exactly that. The needle point allows for extreme precision without catching on the paper texture.

Premium feel and performance
This is definitely a premium product. The build quality is solid, and the special jade design makes it stand out. Slightly pricey compared to standard liners, but worth it for the reliability.
Q: Is the ink archival safe?
A: Yes, the oil-based pigment ink used in this pen is acid-free, lightfast, and waterproof, making it suitable for archival artwork and documents.
Q: Is this pen suitable for use on dark paper?
A: This specific model features black pigment ink designed for high contrast on white or light-colored paper. For dark paper, we recommend our white gel ink series instead.
Q: Does the cap seal tightly to prevent drying?
A: Yes, the pen features a secure click-cap mechanism designed to create an airtight seal, protecting the oil-based ink from drying out when not in use.
Q: How does the 0.05mm compare to the 0.1mm version?
A: The 0.05mm offers an ultra-fine line ideal for extreme detail work like hair strands or texture in carving sketches, while the 0.1mm provides a slightly bolder line better for general outlining.
Q: Can the ink cartridge be refilled?
A: No, the CS-200PN is a disposable fineliner pen. Once the ink is depleted, the entire pen should be recycled according to local regulations.
