Smooth and quick-drying, enduring good writing
- The DuraBall® pen tip has both the ease of writing and the stability of a bullet tip.
- Using pigment ink, writing is smooth and fluent, quick-drying and not easy to scratch.
- The single writing distance is about 800 meters, which is twice the standard requirement, and the large-capacity writing is more durable.
- The diamond pattern hard rubber pen grip makes writing grip more non-slip.
