Protective cases are designed to safeguard electronic devices, such as smartphones, tablets, and laptops, from damage. They are typically made from materials like silicone, plastic, or leather, providing a barrier against impacts, scratches, and dust. Many cases also offer features like water resistance and shock absorption to enhance protection. In addition to physical protection, protective cases can also improve grip and prevent accidental drops. Some cases come with added functionalities, such as built-in stands or cardholders, making them more versatile. Popular brands like OtterBox and Speck are known for their durable and stylish protective cases.
