Set of 4 coasters. Washable. Size is approximately 11 cm (4.3 inches) in length and width. Besides coasters, you can use them for various purposes such as placing accessories or watches, or under a mini vase. They are slightly thick because a batting material is sandwiched inside. They absorb condensation from cold drinks in the summer, preventing the table from getting wet. Please read the profile before purchasing. Serving ware... Coasters Material... Fabric Serving ware...
