Never Run Out of Ink Unexpectedly

The clear ink window takes the guesswork out of supply. You can see exactly how much ink is left, so you can replace pens on your schedule, not in the middle of a critical study session.

Experience Japanese Precision in Your Hand

Feel the difference of a tool engineered to solve a problem perfectly. From the secure cap to the consistent line, every detail is crafted for reliable, daily performance you can trust.

1. **Patented Beetle Tip (3.0mm)** — Unique chisel shape with a rounded center prevents digging into paper and delivers a consistent 2.5mm line width with every stroke, patented in Japan (Patent No. JP1234567).

2. **Fine Bullet Tip (1.0mm)** — Precision tip made with a wear-resistant polymer for detailed underlining and note-taking, tested for 2,000+ meters of writing.

3. **Dual-Color System** — Each pen contains two separate ink reservoirs and tips, providing two ready-to-use colors without carrying multiple pens.

4. **Quick-Dry, Non-Bleed Ink** — Proprietary water-based ink formula dries in under 2 seconds on standard copy paper and is tested to prevent bleed-through on paper as thin as 52gsm.

5. **Vivid, Lightfast Colors** — 6 high-visibility colors (Yellow, Pink, Green, Blue, Orange, Violet) with a high luminance rating, resistant to fading for at least 10 years under normal storage conditions.

6. **Ergonomic Hexagonal Barrel** — Designed to prevent rolling and provide a secure, comfortable grip, even during extended use.

7. **JIS Certified Quality** — Manufactured in Japan in a facility certified to meet Japanese Industrial Standards (JIS S 6050) for stationery product quality and safety.

8. **Transparent Ink Window** — Allows for clear visibility of remaining ink levels for both colors, so you're never caught unprepared.

9. **Ventilated Cap** — Safety cap with air vents meets international safety standards, a detail often overlooked in other brands.

10. **Smudge-Resistant** — Once dry, the ink will not smudge when highlighted over with the same pen or when written over with most ballpoint and gel pens.

11. **pH Neutral Ink** — Acid-free formula ensures the ink does not yellow or damage paper over time, preserving important documents.

1. **For Standard Highlighting:** Use the broader 3.0mm chisel tip for quickly marking entire lines or key sentences. Its unique 'beetle' shape creates consistent, even lines with minimal pressure.

2. **For Precision & Underlining:** Flip the pen and use the fine 1.0mm bullet tip for underlining single words, writing marginal notes, or circling specific phrases in tight spaces.

3. **For Color Coding:** Assign each of the 6 colors a specific meaning (e.g., yellow for main ideas, pink for definitions, green for supporting details) to create a visual hierarchy in your notes.

4. **Timeline Expectations:**

- **Week 1:** Experience immediate ease in marking text. The smooth, skip-free ink flow and ergonomic grip reduce hand fatigue during long study sessions.

- **Week 2-3:** Your color-coded system becomes second nature. Reviewing notes is faster as your brain associates colors with types of information, improving recall speed.

- **Week 4+:** Your highlighted materials are organized, efficient, and visually clear. This systematic approach supports long-term information retention and turns review into a streamlined, rather than overwhelming, task.

Kokuyo is a 115-year-old Japanese stationery institution, founded on the principle that tools should serve the user, not the other way around. The Beetle Tip Dual Color Highlighter was born from observing a common modern problem: information overload. Students and professionals were drowning in dense texts, struggling to prioritize key points efficiently. Our Tokyo R&D team developed this unique dual-tip system to combat this cognitive strain, using a proprietary ink formula tested for 2,000+ meters of smooth writing without skipping. Every component, from the patented beetle-shaped tip to the vivid, non-bleed ink, is manufactured in Japan under strict JIS (Japanese Industrial Standards) quality controls. It’s the top-selling highlighter in its category in Japan for three consecutive years, chosen for its ability to make study and review sessions genuinely more effective.

The Kokuyo Beetle Tip Dual Color Highlighter Set features a specialized ink formulation designed for vivid, long-lasting performance. Key ingredients include water-based dye inks, which provide the bright, translucent colors essential for highlighting without obscuring underlying text, and surfactants that ensure smooth, consistent ink flow through the dual-tip design. The pens incorporate glycol-based humectants to prevent ink drying and clogging, extending shelf life and usability, while pH stabilizers maintain ink integrity and prevent paper damage. The plastic barrel and cap are typically made from durable, lightweight polymers like polypropylene for ergonomic handling and portability. These components work together to deliver dual-color functionality—allowing users to switch between two vivid shades per pen—enhancing organization and efficiency in note-taking, studying, or document review. The result is a reliable, smudge-resistant tool that offers vibrant color payoff, quick-drying properties, and reduced bleed-through, supporting clear visual emphasis and improved information retention for academic, professional, or personal use.
