These crystals are a boon to causing two surfaces to slide apart. They react much as fanning powder did on playing cards. In fact if you use cards this will replace that old powder and last 10 times longer. When applied to paper, the surface may be wiped with your hand and no feeling of a coating will be detected. In point of fact, I have applied them to the pages of a book, wiped the pages with my hand several times and it made no difference to the operation. Unlike other powders this will standup to repeated use. The books that I have applied my crystals to have yet to not work as they did when first applied. As of this writing, I have tried to get the pages to fail over 90 times and yes they are still working. Therefore I can not tell you how long they will last. A third of an ounce is supplied in a glass bottle with a roller ball applicator. No effect is provided. Once in your position many applications will come to you or buy Hoy Outdone, listed elsewhere in this catalog.
