Swiss Precision Craftsmanship – The Unicorn 7 Year Pen

"A pen designed to last seven years." Precision crafted and manufactured in eco-conscious Switzerland. Each pen contains a generous amount of ink, enough to draw a continuous line 4 to 5 kilometers long. We did some math (1 to 2 meters of ink written daily, multiplied by 365 days, multiplied by seven years) and came up with the name: "The 7 Year Pen." Writes 1.7 meters daily for up to 7 years, with an ultra-durable tip and smooth, pure black ink. Designed in harmony with ecology – a pen that can change the world. The 7 Year Pen is refillable, so you don't have to discard the entire pen when the ink runs out.
