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 improve the grip of devices, making them less likely to slip from hands. Some cases come with added functionalities, such as built-in stands or cardholders, making them versatile accessories for everyday use.
