A bag is a flexible container made from various materials, such as fabric, plastic, or leather. It is designed to hold and carry items, making it a practical accessory for everyday use. Bags come in many shapes and sizes, including backpacks, tote bags, and purses, each serving different purposes. Bags often feature handles, straps, or zippers for easy transport and access. They are commonly used for shopping, travel, and storage. Some bags, like luggage, are specifically designed for carrying clothes and personal items during trips, while others, like diaper bags, are tailored for parents to carry baby essentials.
