Permanent markings are designs or symbols that are intended to last for a long time, often created on surfaces like skin, metal, or paper. A common example is a tattoo, which is a form of body art made by injecting ink into the skin. These markings can hold personal significance, represent memories, or simply be a form of self-expression. In addition to tattoos, permanent markings can also be found in various industries. For instance, engraving is used to create lasting designs on items like jewelry or tools. These markings serve both decorative and functional purposes, ensuring that important information or artistic designs remain visible over time.
