Noodler’s Ink Properties....as per Noodler's Ink website:

“Bulletproof Ink” is a term that may be a perpetually changing measure. As Noodler’s developed greater durability in its inks, the definition of “bulletproof” evolved to accommodate new durability. When first described in Greg Clark’s “Ink Sampler” magazine many years ago it generally referenced water resistance and some other archival qualities. Later the term evolved to include resistance to an increasing array of industrial solvents and bleaching agents and other tools of the forgers – and severe tests in the Arizona sunlight over many months (as well as heat lamps, ageing ovens, biological attacks in moist conditions – Hurricane Katrina situations for example – among many further tests…).

As a certified retailer for Noodler's Ink® I am able to only list their products at their recommend MSRP. Other certified retailers of this manufacturer are given the exact same guidelines. Should you see prices under the MSRP, I would caution you as to whether or not you are receiving an item from a certified retailer of this manufacturer. Purchasing items from non-certified retailers may invalidated your guarantee. However, only the manufacturer can address that issue with certainly. Remember buying below MSRP may not actually represent a "savings".
