Reliable for signing documents
While marketed for drafting, I love using this for signing important contracts. The waterproof feature gives me peace of mind that the signature won't fade or smear over time.

Great quality, wish it was refillable
As a disposable pen, the quality is unmatched. The flow is smooth and never skips. My only complaint is that I wish Rotring made a refillable version of this specific direct liquid model.

Smooth writing experience
Very comfortable to hold for long drawing sessions. The grip is textured enough to prevent slipping. Deducting one star only because the cap can be a bit tight sometimes.

Perfect for architectural sketches
The line consistency is incredible. I use these for my final presentation boards and the waterproof ink ensures my work stays crisp even if I accidentally spill water nearby.

Consistent line width every time
Precision is key in my line art, and this pen delivers exactly what is promised. No blobbing at the start or end of a stroke. Highly recommended for professionals.

Best pen for technical illustration
I have tried many brands, but nothing beats the German engineering of Rotring. The tip does not fray, and the black is deeply saturated. Essential for any designer.
Q: Is the ink truly waterproof once it dries?
A: Yes, the direct liquid ink is formulated to be waterproof and lightfast once fully dried, making it suitable for archival work.
Q: Is the tip durable enough for rough sketching surfaces?
A: The tip is made of hardened stainless steel, which is quite durable. However, for the best longevity and line consistency, we recommend using it on smooth to medium-texture papers.
Q: What is the exact line width of this specific model?
A: This specific SKU features a 0.35 mm line width. We offer various other sizes ranging from 0.18 mm to 1.0 mm if you need different thicknesses.
Q: How long does the ink last if I don't use it daily?
A: Since this is a disposable pen with a sealed cap, the ink remains viable for several years if stored horizontally with the cap tightly secured to prevent drying out.
Q: Can this pen be used on tracing paper without bleeding through?
A: Absolutely. The fine stainless steel tip and controlled ink flow are designed specifically for use on thin papers like tracing paper without bleeding or feathering.
