A laptop bag can have multiple compartments where you can store your laptop, accessories, or additional documents. It comes with a handle or strap that makes it easier to carry around. While a laptop case only acts as a protective shell that fits into your laptop to protect it from dirt or scratches. It adds an extra layer of protection to your laptop. Meanwhile, a laptop sleeve is a lightweight cover made of soft, stretchy materials that protects your laptop from scratches and minor damage.
