Q&A

Is this pen safe for writing bank checks?

Yes, this writing tool is highly recommended for security purposes. The archival-quality ink is specifically engineered to prevent "check washing" by physically bonding to the paper fibers. It is resistant to water and common chemical solvents used by fraudsters, ensuring your financial documents remain tamper-proof.

What does pigment-based ink mean?

This refers to ink containing solid color particles rather than liquid dyes. These particles are much larger and stay on the surface of the page, which provides superior resistance to water and sunlight. This technical property ensures that the writing is fade-resistant and permanent over long periods.

Why choose a broad tip for signatures?

A larger 1.0mm tip provides a thicker line that is easier to read and scan digitally. It offers a more authoritative look for official documents and reduces the friction felt while writing. This creates a smoother, buttery experience that minimizes hand fatigue during long signing sessions.
