A band-aid is a small adhesive strip used to cover minor cuts and scrapes on the skin. It usually consists of a soft, absorbent pad in the center that protects the wound, surrounded by a sticky material that keeps it in place. Band-aids come in various sizes and designs, making them suitable for both children and adults. They help keep dirt and germs out, promoting faster healing. In addition to their practical use, band-aids often feature fun designs, like cartoon characters or colorful patterns, appealing to kids. Some band-aids even have special properties, such as waterproofing or antibacterial features, to enhance their effectiveness.
