A product designed specifically for collectors. Clarity Watermark Fluid is a true innovation in the technology of expertising stamps, combining the clearest possible watermark images with safety for the stamps and the collector.
Clarity is the only watermarking fluid that was developed under the guidance and with the cooperation of the American Philatelic Society. Clarity is non-flammable, non-toxic, and is completely safe for the environment.
This stamp watermark fluid is available in a 3.4 fluid ounce (100 ml) convenient flip-top bottle.
