Drink coasters are small, flat objects designed to protect surfaces from moisture and heat damage caused by beverages. They are typically made from materials like cork, wood, ceramic, or silicone, and come in various shapes and sizes. Coasters help prevent rings and stains on tables and countertops, making them a practical addition to homes and restaurants. In addition to their protective function, drink coasters can also serve as decorative items. Many coasters feature unique designs, patterns, or images, allowing them to complement the decor of a room. Some coasters even have fun themes or are personalized, making them popular gifts for occasions like housewarming parties or weddings.
