It is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to paper fibers. It is resistant to chemicals that wash dye-based ink from checks. Super ink is also fade resistant, water resistant, and acid free. The ballpoint pen has a unique ‘Uni-Flow’ system that ensures ink flows consistently to give you a smooth writing experience down to the last drop – so there’s no need to worry about the pen jamming or ink suddenly running out. It writes with a bold, 0.7mm nib to create a fine, 0.5mm line that will work great for note taking or general writing. A stainless steel tip with a tungsten carbide ball ensures that this ink pen will never break when you need it the most. The capped top stays put and ensures that this pen will never leak in your pocket.
