International pictorial markings like This Way Up, Fragile, Do Not Stack, etc. have certain display requirements by ISO like -  - Symbols should preferably be stenciled directly on the package or may appear on a label. - Symbols need not be framed by borderlines. - The color used for symbols should be black. If the color of the package is such that the black symbol would not show clearly, a panel of a suitable contrasting color, preferably white, should be provided as a background. - Some handling instructions have specific display requirements like “Fragile” and “This Way Up” should be shown near the left-hand upper corner on all four upright sides of the package.
