The JG100 Jack Guard will perfectly seal any quarter-inch input and output jack and provide powerful antistatic protection that repels smoke, dirt, and dust particles away from the installed jack. A newly created material called Plasiccant enables the Jack Guard JG100 to quickly absorb ambient moisture from your instruments and equipment's interior cavities. It provides continuous moisture control for up to one year. The JG100 Jack Guard was designed for all quarter-inch input/output jacks. Guitars, amps, effect pedals, keyboards, soundboards, and home audio systems are exactly what the Jack Guard products are designed to protect. The JG100 model can be reconstituted and reused over and over again. All Jack guards will last for the lifetime of your equipment and instruments. https://trademarks.justia.com/985/02/plasiccant-98502519.html
