Best value for students

Bought these for my architecture studio class. They last longer than expected and the ink doesn't dry out quickly even if left uncapped for a few seconds accidentally.

Great flow, sturdy build

The dual tips are very convenient when switching between detailing and outlining. The ink flows smoothly without skipping. Only giving 4 stars because I wish they were refillable.

Smooth and dark

The black is very deep and opaque, making scans look crisp. The grip is comfortable for long drawing sessions. Would recommend keeping the caps on tight to preserve ink life.

Perfect for the ARE Exam

I used these specifically for my Registered Architect exam prep. The line weights are distinct and consistent, which is crucial for clear technical drawings. No bleeding through standard tracing paper.

Reliable for professional work

As a landscape architect, I need precise lines for site plans. These pens deliver exactly that. The 0.2/0.3 combo is my favorite for intricate hatching patterns.

Essential toolkit item

These have replaced my old single-tip pens. Having two sizes on one barrel saves space in my pencil case. Highly recommended for anyone doing manual drafting.
