Tired of highlighter nibs that fray, leak, or dry out mid-use? Fed up with scratchy tips that ruin your notes or uneven ink flow that blurs important details? We hear you—and we’ve solved the problem with a material revolution: our highlighter nibs are crafted from premium PP (Polypropylene) and PE (Polyethylene), two engineered polymers that redefine what a highlighter can do. Say goodbye to frustrating marking experiences and hello to a nib that’s as reliable as it is versatile—designed for students, professionals, and anyone who demands precision and durability.

Not all nib materials are created equal. After rigorous testing of fibers, plastics, and composites, we chose PP and PE for their unbeatable combination of performance, safety, and longevity. Here’s why they stand out:

Your health matters—and so does the quality of your work. PP and PE are food-grade, BPA-free materials that emit no odors and release zero harmful substances. Perfect for students who spend hours highlighting textbooks or professionals drafting reports, they’re gentle on skin and safe for daily use. Plus, their exceptional chemical stability means they won’t react with alcohol-based or water-based highlighter inks. No more discolored ink, corroded nibs, or unexpected leaks—just consistent, reliable performance from the first stroke to the last.

How many times have you tossed a highlighter because the nib frayed, bent, or split? Our PP/PE nibs are engineered to withstand heavy use. PP offers the ideal balance of rigidity and toughness, resisting pressure without collapsing or breaking. PE adds a layer of flexibility, bouncing back quickly after being pressed—eliminating the "frayed bristle" look that plagues traditional fiber nibs. Whether you’re highlighting 100 pages of notes, tossing your highlighter in a backpack, or using it daily for months, our nibs stay intact. On average, they last 30% longer than standard fiber or plastic nibs—saving you money and reducing waste.

The best highlighter nibs feel like an extension of your hand—gliding across paper, delivering ink evenly, and responding to your pressure. PP and PE’s molecular structure creates natural capillary action, with tiny, uniform pores that absorb and release ink with precision. No more blobbing, skipping, or dry spots. Press lightly for thin, precise lines (perfect for underlining keywords) or apply more pressure for bold, wide strokes (great for highlighting sections). Even if you leave the cap off overnight, the nib retains moisture—just one stroke reactivates the ink, no tedious scribbling required.

From humid classrooms to dry office environments, our PP/PE nibs perform consistently. They resist heat, moisture, and temperature changes, so you won’t find them softening in summer or cracking in winter. Unlike fiber nibs that absorb humidity and clump, or cheap plastic nibs that harden over time, PP/PE maintains its shape and performance in any setting. Whether you’re studying outdoors, commuting, or working from home, your highlighter will be ready when you are.

We don’t believe in one-size-fits-all. That’s why we’ve crafted four specialized nib shapes, each optimized to leverage the unique strengths of PP and PE—so you can choose the perfect tool for your workflow:

Ideal for everyday use, this iconic axe shape is made with a PP core for maximum durability. The smooth, burr-free cut lets you switch seamlessly between thin and wide lines by adjusting your grip. Highlight entire paragraphs with the wide edge or underline terms with the narrow tip—perfect for textbooks, reports, and meeting notes. PP’s rigidity ensures consistent performance, even with repeated use.

Designed for comfort and precision, this 30-degree angled nib features a PE core that glides softly across paper. The tilt fits natural writing habits, reducing wrist strain during long study sessions. PE’s flexibility ensures the nib stays in contact with the page, delivering even ink flow without covering underlying text. Great for dense notes, journaling, or detailed annotations—you’ll wonder how you ever used a straight nib.

Why choose one nib when you can have two? Our dual-tip highlighters pair a PP wide tip (4.0mm) with a PE fine tip (0.8mm). The PP side handles large-area highlighting and title marking—tough enough to withstand heavy pressure. The PE side is perfect for writing comments, underlining small text, or adding details. It’s the ultimate multitasking tool for students, teachers, and professionals—one pen replaces two, saving space in your bag.

On-the-go? This nib is built for portability. A rigid PP base secures the nib to the pen barrel, while a flexible PE gasket creates an airtight seal. No more ink leaks in your backpack, purse, or laptop bag—even if you invert the pen. The PE nib itself is soft enough for smooth writing but durable enough to handle travel bumps. Perfect for commuters, travelers, or anyone who needs a reliable highlighter on the move.

Say goodbye to frayed, leaky, inconsistent highlighters. Our PP/PE nibs aren’t just a small upgrade—they’re a complete reimagining of what a highlighter can be. Safe, durable, smooth, and versatile, they’re designed to make your marking experience easier, more efficient, and more enjoyable.

Whether you’re a student prepping for exams, a professional organizing reports, or someone who loves neat, clear notes, our PP/PE nib highlighters are built for you. Experience the difference that premium materials make—order yours today and elevate your highlighting game.
