TUL Colored Gel Pen Set | Vibrant Ink in 8 Bold Colors
Our TUL colored gel pen set brings bold, vibrant ink to every page. This 8-piece collection includes red, orange, yellow, green, blue, purple, pink, and teal gel pens with smooth-flowing 0.7 mm medium points. Each pen features our signature cushioned grip for long writing sessions and a retractable tip that protects pockets and bags. The quick-drying gel formula resists smudging and feathering on most paper types, making it ideal for journaling, class notes, planners, and creative projects.
Quick specs for the TUL colored pen set
Gel Ink Formula and Flow Performance
The TUL colored pens use a hybrid gel suspension that balances pigment density with smooth flow. Each cartridge holds 0.5 mL of water-based gel ink with a viscosity of 1800–2200 cPs, low enough to glide across paper without skipping yet thick enough to prevent bleed-through on lightweight sheets. We incorporate polymer binders that lock pigment to cellulose fibers within two seconds of contact, which is why the ink dries faster than many liquid rollerball formulas.
Grip Comfort and Barrel Ergonomics
We shaped the TUL barrel with a 10 mm diameter grip zone, slightly wider than the industry standard 8 mm, to distribute pressure across more surface area of your fingers. The cushioned rubber sleeve compresses under typical writing force, creating a custom contact profile that reduces hotspots during extended note sessions. The grip texture features micro-ridges spaced 0.8 mm apart, enough to prevent rotation without feeling abrasive against skin.

Common Questions About TUL Colored Gel Pens
Yes, every TUL colored gel pen in this set accepts standard TUL gel refills. The barrel uses a twist-lock mechanism that lets you replace the cartridge without tools. We sell individual color refills and multi-packs separately, so you can keep using the same comfortable pen body for months.
The TUL colored gel pen set features 0.7 mm medium point tips. This size produces bold, visible lines that are thick enough for highlighter-style emphasis but fine enough for normal handwriting. If you prefer thinner lines for detailed notes or small script, we also offer a fine point version with 0.5 mm tips in the same color range.
The quick-dry gel formula dries within two seconds on most coated and glossy papers, including photo paper and cardstock up to 110 lb weight. On extremely high-gloss or plastic-coated surfaces, you may see minor smearing if you touch the ink immediately. For best results, allow three to five seconds of dry time on non-porous materials.
Yes, the fast-drying ink and cushioned grip work well for left-handed writers. The gel formula sets quickly enough that most left-handers won’t smudge lines as their hand moves across the page. The grip texture is symmetrical, so there’s no right-hand bias in the barrel design.
Each TUL colored gel pen cartridge contains 0.5 mL of ink, which translates to approximately 400–500 meters of continuous writing. For typical note-taking or journaling—around 2–3 pages per day—you can expect each pen to last two to three months. Heavier users who write 10+ pages daily may need refills every four to six weeks.
Yes, all eight colors use acid-free gel formulations with archival-quality pigments. We test each batch for lightfastness to ASTM D6901 standards, and the inks retain at least 85% of their original color after six months of equivalent sunlight exposure. This makes them suitable for scrapbooking, journals, and documents you want to preserve long-term.
The TUL colored gel pens perform well on paper weights as low as 20 lb without significant bleed-through. The water-based gel ink absorbs into cellulose fibers quickly, minimizing ghosting on the reverse side. For best results on very thin paper like onion skin or airmail stock, use lighter pressure and allow the ink an extra second to dry before turning the page.
