A drawstring bag is a lightweight, casual bag that typically features a simple design and a drawstring closure at the top. The bag is often made of soft, durable materials like cotton, canvas, or nylon, and it may come in a variety of sizes and colors.

The drawstring closure of the bag allows for easy access to the contents, while also providing a secure way to keep them in place. The user simply pulls the strings tight to close the bag, and then loosens them to open it again. This makes drawstring bags a popular choice for carrying small items like gym clothes, books, snacks, or personal belongings.

Overall, drawstring bags are a versatile and practical option for anyone who needs a simple and convenient way to carry their belongings.
