MarkMate Ti Pen | One Pen, Infinite Possibilities

Have you ever imagined a pen that seamlessly integrates writing, measuring, and marking? 

Well, MarkMate delivers!

It rests in your pocket, ready to answer every creative spark—no searching, no losing, no compromising.

It started with those all-too-familiar moments:

• Creative Flow Broken
  Searching frantically for a ruler during sketching, or finding yourself without marking tools during on-site work—even resorting to a crumpled receipt as a makeshift measuring tape.
• Lost Inspiration
  Rummaging through cluttered tools to find the right one, only to watch your brilliant ideas slowly fade away.
• Bookmarks That Vanish
  Traditional bookmarks constantly slipping out of pages, losing your reading progress—forcing you to dog-ear the pages as a last resort.

Now, it's time to end the awkwardness.

Machined from Gr5 titanium, this 6mm ultra-slim companion disappears into your notebook, yet unfolds into an entire precision drafting kit when needed.

It’s a ruler when you need precision, a protractor for angles, a caliper for measurements, a bookmark when inspiration strikes.

But here's the really cool part - that satisfying pull-twist action you'll love fidgeting with. It's not just a refill mechanism; it's a tiny mechanical wonder that locks the ink in place with precision you can actually see and feel. Go ahead, play with it - we promise you won't be able to stop.

Whether you're a designer sketching prototypes, an engineer jotting calculations, a student taking notes, or just someone who appreciates beautifully crafted tools - this is your everyday essential.

 So,Why keep switching between tools when one should be enough?

The vision was simple: one tool to replace many, without compromise. But achieving that required rethinking every detail from the ground up.

So we reimagined what a pen could be—not by adding more, but by designing smarter.

The MarkMate isn’t just a collection of features—it’s a unified system where every design choice serves a purpose.

Its flat profile isn’t just for style—it’s functional. The unique shape prevents rolling, doubles as a bookmark, and offers a surprisingly comfortable and stable grip whether you’re writing for hours or measuring on the go.

At just 6mm thin, the MarkMate is slimmer than a standard pen, yet thicker than a coin—engineered to be both remarkably compact and unexpectedly substantial. It effortlessly slips between notebook pages or into your pocket, vanishing until you need it. No bulk, no clutter—just pure, always-ready utility.

Crafted from aerospace-grade Gr5 titanium with brushed brass accents, the MarkMate is built for a lifetime of use. It’s rust-proof, lightweight, and tough enough to survive daily carry, while developing a unique patina that tells your story.

The titanium provides strength and lightness, while the brass adds warmth and sophistication—a perfect union of durability and elegance.

Behold the perfect equilibrium: MarkMate rests effortlessly on a single fingertip. This isn't just lightweight—it's precision weight distribution achieved through advanced titanium engineering, offering enduring performance that feels virtually weightless.

Forget everything you know about how pens work. Meet the pull-twist action—a satisfying two-step motion that brings your refill forward with tactile precision. Gently pull the titanium tip to reveal the mechanism, give it a half-twist, and it locks firmly into place. No buttons, no clips, no play—just solid, reliable writing the moment inspiration strikes.

And when you’re done? A reverse twist retracts it seamlessly. It’s intuitive, fidget-friendly, and designed for pure one-handed operation.

Now that you've seen the design, let's explore its capabilities in detail.

The MarkMate adapts to your life and your style of carry.

The Bookmark: Slip it seamlessly between the pages of your notebook or novel.

The Pocket Clip: Securely attach it to a pocket, backpack strap, or organizer.

Free-Float: Simply drop it into any pocket or bag compartment. Its durable titanium construction can handle it.

At its heart, MarkMate is a superb writing instrument. The unique pull-twist mechanism securely advances and retracts a standard D1 refill, ensuring no wobble and a reliable line every time.

Refill Compatibility: Uses universally available D1 refills in black, blue, red, or even gel ink.

Any D1 refill can be used in MarkMate pens, including but not limited to the types pictured below:

How to Replace: Unscrew the titanium tip, remove the spring, slide out the old refill, and slide in a new one. It’s a 10-second process that ensures a lifetime of writing.

Integrated seamlessly into the end of the pen, our protractor offers 180 degrees of precision measurement.

Magnetic Closure: A satisfying magnetic snap keeps it closed when not in use and makes it easy to deploy with one hand.

Precision Markings: Each of the 12 markings represents 15 degrees, allowing for quick, accurate angular measurement on the fly.

The side edge of the MarkMate is a precision-machined ruler, ready for quick measurements whenever inspiration strikes.

Dual Scales: We offer both metric (mm/cm) and imperial (inch) scale versions.

Precision Scale Engineering
• Permanent Markings: Created through deep-laser etching technology
• Wear-Resistant: Composite-infilled grooves withstand daily abrasion

Your Choice: Let us know your preference in the backer survey after the campaign! Measure everything from quick sketches to component sizes.

Go beyond simple length measurements. The sliding jaw allows you to accurately measure outer dimensions and depths of small objects.

See How to Use the Measuring Features Below:

Measurement Range: Precisely measure objects from 0 to 40mm (approx. 0 - 1.5 inches). Perfect for electronics, jewelry, modeling, and countless DIY tasks.

Engineered for readers and thinkers, the MarkMate is the ultimate page-marker. Its ultra-slim, flat profile slips perfectly between pages without bulging or damaging paper.

Secure Grip: The precise machining and material weight ensure it stays exactly where you place it, unlike flimsy paper bookmarks that slip away.

Instant Access: Your pen is always right there when inspiration strikes mid-page. No more digging for a writing tool—it’s already in your hand.

Elastic Pen Sleeve：We offer an optional elastic pen sleeve featuring an adjustable strap that snugly fits books of various sizes. If you're interested, you can add this accessory in the Add-on section later.

For ultimate visibility and a touch of personalized style, the MarkMate features eight precision-machined slots for tritium vials.

Full Customization: Four slots are sized for 2x12mm vials and four for 1.5x6mm vials, distributed on the front and back for a balanced glow. This allows you to create a unique lighting pattern that’s truly your own.

Your Choice, Your Style: Install all eight vials for maximum visibility, create a subtle pattern with just a few, or leave them empty for a sleek, minimalist look. The titanium slots themselves are a detailed design feature even without vials.

Design Sketches: Where Vision First Met Paper

It began with simple lines on a page—early concepts of a pen that could also be a bookmark, a ruler, a tool. These initial sketches weren’t just drawings; they were the first physical whispers of the MarkMate idea. Interestingly, the protractor wasn’t even part of the earliest vision. It was only through iterating on these sketches that we realized: the end of the pen could become something more.

Through meticulous line drawings, dynamic 3D modeling, and iterative prototyping, every detail of MarkMate was digitally and physically refined. The transition to precision CNC milling then carved these designs into aerospace-grade titanium, transforming digital plans into tangible excellence. Rigorous validation ensures each component functions as harmoniously as intended. This is more than a pen—it's a promise engineered through process.

Sample Validation: Where Design Meets Reality

The final test. Fully functional samples underwent rigorous validation—measuring accuracy, testing durability, writing under pressure, and even verifying the satisfying “click” of the mechanism. This is where we ensured the MarkMate doesn’t just look exceptional—it performs exceptionally.

Crafted with intention and validated with precision, the MarkMate is more than a product—it’s a promise delivered through process. We didn’t just design a pen. We engineered a new way to create.

That's a wrap! Thank you for your support and for joining the MarkMate journey. We can't wait to get this pen into your hands!
