There’s a fine line between a pen and a marker- literally! It’s called the Pfeiffer uWrite Fineliner. Perfect for everything from writing to underlining, the uWrite Fineliner is completely metal-free, and 100% non-toxic. The needle-shaped nib, which is housed in a polymer tip, produces a fine 0.4 mm line width. The uWrite Fineliner is also water-resistant and document proof.
Plus, when your uWrite Fineliner eventually runs out of ink, you can just slip in a Pfeiffer refill, and get straight back to work.
With the Pfeiffer uWrite Fineliner, everything from the refill, made from a single class of plastic, to the metal-free body and polymer tip has all been engineered with sustainability in mind. You can write away with an environmental conscience that is just fine.
