A coaster set is a collection of small, flat objects designed to protect surfaces from beverage stains and heat damage. Typically made of materials such as wood, cork, ceramic, or silicone, coasters are commonly used on tabletops, counters, and other furniture. They are designed to provide a stable and secure resting place for cups, mugs, glasses, and bottles. Coaster sets often come in matching designs or themes, making them not only functional but also aesthetically pleasing. They are a popular accessory for homes, offices, and hospitality establishments, serving as both practical items and decorative accents.
