Classification I: "Freeze Resistant Inks" include Polar Blue and Polar Black, which will resist forming a solid mass of ice within a glass ink bottle during most cold weather conditions (though they will form some harmless ice "slush" when very cold). The first "Polar" ink was "freeze proof" to -114° F, but the reformulated Polar inks made from 2006 and later have a faster dry time, better flow rate, and are basic "freeze resisting" inks to avoid expansion barrel cracks in pens and broken bottles in mail boxes on cold days. | ||

Classification II: "Eternal" refers to any Noodler's Ink that resists the effects of time - moisture, humidity, UV light, acids, water exposure, and many common detergents such as dish soaps and household ammonia, as well as alcohols and acetone (which conventional ball point pens have no resistance to - often rinsing off a newly written check within 8 seconds of being washed with acetone). | ||

|
|
Classification III: "Bulletproof" refers to any Noodler's Ink that resists all the known tools of a forger, UV light, UV light wands, bleaches, alcohols, solvents, petrochemicals, oven cleaners, carpet cleaners, carpet stain lifters, and of course...they are also waterproof once permitted to dry upon cellulose paper. | ||
