These coasters are sold in sets of four, and a minimum purchase of two sets is required. This felt coaster set is made with about half-inch of felt balls. Each felt ball has been hand-stitched to each other. It is heat resistant so it can protect your tabletop from burning from the hot cup. ***Customize Your Order: Tailor your trivet or coaster to your preferences. We craft each piece on demand, allowing you to choose the color, shape, and size that suits you best. Reach out via DM to discuss your ideal style.*** * Size: Approx.
