A thin, substantially flat packaged unit includes a thin, substantially flat utensil in a protective sheath. The protective sheath includes a flat rigidifying member of substantially the same thickness as the utensil and surrounding marginal edges of the utensil, and flexible sheet material overlying the utensil and adhered to the rigidifying member. In a preferred construction the utensil includes a substance that is interactable with a fluid, and the protective sheath encloses at least the section of the utensil including the substance. |
