Precision Swiss Craftsmanship - The Cocktail 7 Year Pen

"A Pen Claimed to Last Seven Years" Designed and Manufactured with Precision Swiss Craftsmanship, a Commitment to Eco-Friendliness. Each pen contains an abundant amount of ink, enough to draw a continuous line 4 to 5 kilometers long. We did some quick calculations (1 to 2 meters written daily x 365 days x 7 years) and arrived at the title: "The 7 Year Pen." Write 1.7 meters daily for up to 7 years, with an ultra-durable nib and smooth-flowing pure black ink. Design and ecology in harmony – 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.
