## Description

The reliable Uni-ball Eye Micro rollerball pen has been a world favorite for more than 20 years. What makes the Uni-ball eye unique is the ‘Uni-Flow’ system ensures ink flows consistently to give you a smooth writing experience down to the last drop. No need to worry about the pen jamming or ink suddenly running out. An internal regulator inside the ballpoint pen controls the flow of ink, stores the excess, and expels the air before it reaches the tip, ensuring your lines will never break in mid stroke. The Eye Micro contains uni Super Ink which is fade resistant, water resistant and tamper proof. You can create ultra-fine lines with a 0.5mm nib, making it perfect for technical writing and small printing. A stainless steel tip with a tungsten carbide ball ensures that this rollerball pen will never break when you need it the most. It offers a comfortable grip that is great for left or right handed users, and ensures you can keep writing all day long. The capped top also stays put and ensures that this pen will never leak in your pocket. Black ink pens in a box of 12.
