TUL Ballpoint Pen Fine Point | Precision Writing Tool
Our fine point ballpoint pen delivers consistent, skip-free lines for detailed writing tasks. The 0.7mm tungsten carbide ball tip creates crisp text without bleeding through most paper stocks.
Construction & performance details
Tungsten carbide tip engineering
The 0.7mm ball is precision-ground from tungsten carbide, one of the hardest materials used in pen manufacturing. This hardness ensures the tip maintains its spherical shape through thousands of writing strokes, preventing the flat spots that cause skipping in cheaper ballpoints.
Refillable cartridge system
Each pen accepts TUL fine point refills, which snap into the barrel without tools. The refill houses approximately 1.2 kilometers of writing length in standard conditions. When ink runs low, you’ll notice lighter lines before complete depletion—giving you time to swap cartridges mid-project.

Common questions about the TUL fine point ballpoint pen
The pen produces a 0.7mm line width, suitable for detailed writing tasks like filling out forms, annotating documents, and writing in small planner boxes. This is narrower than our medium point pens, which create 1.0mm lines.
Yes, the pen accepts TUL fine point refill cartridges. To replace the cartridge, unscrew the barrel, remove the spent refill, and snap a new one into place. Each refill provides approximately 1.2 kilometers of writing in typical use. Refills are sold separately in black, blue, and red ink.
The oil-based ink does not bleed through most office paper stocks from 20 to 32 pounds. On very thin paper like Bible stock or airmail weight, you may see slight show-through but typically no bleeding to the reverse side. The ink dries in two to three seconds on standard copy paper.
Yes, the tungsten carbide tip transfers sufficient pressure to create readable duplicates through two or three carbon sheets. Press firmly while writing to ensure clear copies. The 0.7mm tip maintains its shape under repeated pressure, unlike softer ball materials that can flatten over time.
Each refill cartridge contains approximately 1.2 kilometers of writing capacity under standard conditions. Actual longevity depends on your writing pressure, line length, and frequency of use. Most users report several months of daily writing before needing a replacement. You’ll notice lighter lines as the ink depletes, giving you advance warning to order refills.
The barrel is constructed from metal with a rubberized grip section in the middle third. The metal adds weight for balanced writing, while the textured rubber prevents slipping during extended use. The barrel finish is durable enough to withstand daily pocket or bag carry without chipping.
The black ink meets archival permanence standards for records retention and resists fading when stored away from direct sunlight. Blue and red inks resist UV fading for approximately five years under typical office fluorescent lighting. For critical legal or financial documents requiring decades-long legibility, we recommend black ink and acid-free paper storage.
