A cardboard box is a container made from thick paper-based material known as cardboard. It is commonly used for packaging, shipping, and storing items. Cardboard boxes come in various sizes and shapes, making them versatile for different purposes, from moving household goods to packaging products for retail. These boxes are lightweight yet sturdy, providing protection for their contents. They are often recyclable, making them an environmentally friendly option compared to plastic containers. Cardboard boxes can be easily folded and assembled, which allows for efficient storage and transportation when not in use.
