Sustainable and functional

Finally, a technical pen that isn't disposable. Being able to refill it reduces waste, and the performance is just as good as expensive brand-name alternatives.

Architect's dream tool

As an architect, I need precise lines for my drafts. This refillable technical pen delivers exactly that. The ultra-fine tip doesn't fray easily even after heavy use.

Smooth writing experience

No scratching or skipping. The ink flows smoothly onto the paper. I've tried three different ink brands in it, and all worked perfectly.

Perfect for custom ink colors

I love that I can use my own watercolor mixes in this pen. The cotton core absorbs the ink evenly, and the line quality is incredibly consistent for such a fine tip.

Great value, minor learning curve

Excellent pen for the price. It took me a few tries to get the ink saturation right so it wouldn't bleed, but once I figured it out, it writes beautifully.

Good for calligraphy practice

The flexible cotton core allows for slight line variation which is nice for brush lettering practice. Just make sure to cap it tightly to prevent drying.

5 FAQ

Q: What is the best way to clean the pen before changing ink colors?

A: Rinse the cotton core and the nib section under lukewarm running water until the water runs clear. Let it dry completely before adding new ink.

Q: Is the tip size fixed or adjustable?

A: The tip size is fixed at 0.3mm ultra-fine. However, line width can vary slightly based on the pressure applied and the amount of ink saturated in the core.

Q: Does this come with any ink included?

A: No, this product is sold as an empty liner pen with the cotton core installed. You will need to purchase your preferred liquid ink separately.

Q: How do I replace the cotton core when it wears out?

A: Simply unscrew the barrel, pull out the old core gently, insert the new one, and screw the barrel back on. Replacement cores are sold separately.

Q: Can I use alcohol-based inks in this pen?

A: We recommend using only water-based inks. Alcohol-based inks may damage the cotton core and the plastic body of the pen.
