This is a pen that uses low-viscosity, water based gel ink delivered directly from a large-capacity reservoir to the nib via a ballpoint mechanism, ensuring a smooth, skip-free, and quick-drying writing experience.
 
Uses a gel-based, water-based ink that is more fluid than traditional ballpoint ink but thicker than classic rollerball (liquid ink) ink.
This formulation uses pigments rather than dyes, resulting in vibrant, opaque, and often fade-resistant lines.
 
The "straight liquid" design refers to an ink flow system where the ink is delivered from a large-capacity, transparent, ink tube directly to the pen tip without an internal cartridge, which is designed to ensure a consistent and smooth flow.
 
The combination of the smooth-flowing gel ink and the direct-feed mechanism means minimal pressure is needed to write, reducing hand fatigue during long writing sessions.
The result is a fluid, effortless, and consistent line without skipping or clumping.
 
The nib is a precision tip, commonly a 0.5mm fine point made of a durable material, which provides a fine, clear, and precise line suitable for detailed writing, note-taking, and intricate artwork.
 
Transparent pen barrel allows user to monitor the ink level easily and avoid running out of ink unexpectedly.
 
 
Applications:
