Architectural precision

As an architect, I need lines that don't vary in width. This Platinum pen delivers exactly that. The grip is comfortable for long drafting sessions, and the ink flow is smooth from start to finish.

Excellent for technical diagrams

Used this for creating complex circuit diagrams. The line consistency is fantastic. I deducted one star only because the cap can be a bit tight to remove sometimes, but that ensures the ink doesn't dry out.

No bleeding through paper

I was worried about bleed-through on my sketchbook, but this oil-based ink sits perfectly on the surface. It dries instantly and looks very sharp under a magnifying glass.

A joy to hold

Beyond just the performance, the design of this pen is stunning. The translucent green body lets you see the ink level, and the gold trim adds a touch of elegance. It makes drafting feel less like work.

Great pen, but pricey

The quality is undeniable. The jade carving aesthetic is beautiful, and the writing experience is top-tier. My only hesitation is the price point compared to other technical pens, but you get what you pay for.

Perfect for intricate manga work

The 0.05mm line is incredibly consistent. I use this for hair details in my comic strips, and the waterproof ink means I can watercolor over it without any smudging. Highly recommended for artists.

5 FAQ

Q: How long does the ink last if used daily?

A: Usage varies by individual, but for average daily sketching or drafting, one pen typically lasts between 2 to 4 weeks before running dry.

Q: Is this pen suitable for use on tracing paper?

A: Yes, the 0.05mm tip and oil-based ink are specifically designed to work well on tracing paper without feathering or bleeding.

Q: Is this pen safe for left-handed users?

A: Absolutely. Since the oil-based ink dries almost instantly upon contact with paper, it is excellent for left-handed users as it prevents smudging.

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 unit should be replaced to ensure optimal line quality.

Q: Does the 'Jade Carving' refer to the ink color or the pen body?

A: The 'Jade Carving' refers to the decorative design on the pen's barrel and clip. The ink itself is a standard archival black.
