The Wilton Dust-N-Store dusting pouch makes it easy to keep fondant or gum paste from sticking to the work surface or tools with a dusting of cornstarch or confectioners sugar. Youll love the convenience of this easy-to-fill, easy-to-use, easy-to-store dusting pouch system. Since it seals tightly, once you fill it and twist the lid on, the cornstarch or sugar are contained in the food-safe fabric pouch. And when your dusting is done, replace the pouch in the cup and any excess dust is contained securely in the storage cup.
