Abstract: A facial mask includes a permeable sheet and a nanometer metal layer coated on a side of the permeable sheet. The permeable sheet is made of adhesive-bonded fabric and is formed with a nose portion, three openings corresponding to eyes and mouth, and multiple split lines. The nanometer metal layer is composed of nanometer gold particles or nanometer sliver particles. A skin care substance layer is coated on the at least one nanometer metal layer. It is very easy and convenient to clean the facial mask, so the facial mask can be used repeatedly.

Abstract: A portable information device comprises a machine and a tray having slots to contain cosmetic products or body care products. The tray and machine are combined together such that they are slidable, rotationable, or foldable to each other to expose or hide the slots. Alternatively, in a portable information device, a tray is embedded on a cover of a machine, and a plate is above the cover to expose or hide slots on the tray.
