TUL Gel Pen Bold Point (1.0mm) | Premium Writing Instruments
Our TUL bold pens are engineered for writers who need thick, vivid lines that command attention. The 1.0mm tip delivers smooth gel ink flow for signatures, headers, and creative projects where standard pens feel too thin.



Bold-point specifications



Gel ink technology and performance
We use water-based gel ink that combines the bold coverage of a marker with the precision of a pen. The 1.0mm tip deposits a thicker line than standard office pens, which typically range from 0.5mm to 0.7mm. This wider line width makes our bold pens popular with professionals who sign contracts, teachers grading papers, and artists sketching preliminary designs.

Ergonomic design and comfort features
We shaped the barrel with a slight taper and textured rubber grip positioned where most writers naturally hold a pen. The grip diameter measures 10.5mm, which ergonomics research suggests reduces finger strain during extended writing sessions. We’ve received feedback from users who write for 2-3 hours daily that the contoured design prevents the pressure points common with cylindrical pens.

Common questions about the TUL Bold Point Gel Pen
Our TUL bold pens produce lines twice as thick as standard office pens, which typically use 0.5mm or 0.7mm tips. The 1.0mm point is ideal when you need high visibility for signatures, headers, or labels. Writers with large handwriting or those addressing envelopes find the bold width more legible than finer points. If you primarily take notes in small spaces, our medium or fine-point options might suit your needs better.
Yes, our gel ink formula adheres to glossy cardstock, coated envelopes, and photo paper better than standard ballpoint ink. The gel composition bonds with non-porous surfaces more effectively than oil-based ballpoint pens. Allow 5-10 seconds of drying time on very smooth surfaces to prevent smudging. We’ve tested these pens on wedding invitations, business cards, and laminated documents with reliable results.
Each cartridge contains enough gel ink for approximately 1,200 meters of continuous writing. For typical daily use — such as signing documents, writing lists, and taking occasional notes — one pen lasts 2-4 months. Heavier users like teachers grading papers or office professionals signing frequent contracts may need to replace cartridges every 4-6 weeks. We offer refill cartridges that extend the pen’s life without replacing the entire instrument.
Our TUL bold pens work well for both right-handed and left-handed writers. The quick-drying gel ink reduces smudging when your hand moves across fresh writing, which is a common concern for left-handed users. The contoured grip accommodates various hand positions without forcing a specific angle. We recommend allowing 3-5 seconds of drying time between lines if you write very quickly or press lightly, as this ensures the gel sets completely before contact.
We currently offer TUL bold pens in black, blue, red, green, and purple gel ink. Black and blue serve most business and personal correspondence needs, while red is popular with teachers and editors. Green and purple provide options for color-coded organization systems or creative projects. All colors use the same smooth gel formula and produce equally vivid lines. Replacement cartridges are available in each color to match your original pen.
The translucent barrel allows you to monitor ink levels visually without disassembling the pen. When you notice the gel reservoir appearing less than one-quarter full, order a replacement cartridge to avoid running out during important tasks. Most users also notice the ink flow becoming slightly lighter or requiring more pressure when the cartridge nears empty. We recommend keeping a spare cartridge on hand if you rely on these pens for critical documents like contract signings.
The TUL bold pen works well for modern calligraphy styles and casual hand lettering. The 1.0mm tip creates satisfying thick downstrokes when you apply moderate pressure, and the gel ink flows smoothly at various angles. Traditional pointed-pen calligraphy requires specialized flexible nibs, but for everyday decorative writing, headers, and envelope addressing, our bold gel pen delivers consistent results. The retractable design protects the tip between projects, unlike dip pens that require careful storage.
