this black ink is not waterproof/bulletproof.
100% made in the U.S.A...from the cap to the bottle to the ink.
As a certified retailer for Noodler's Ink® I am able to only list their products at their recommended 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".
