These Canvas Home Dauville coasters are a great addition to your home. To use them, simply place them under your cups or glasses to protect your surfaces from moisture and scratches. When it comes to cleaning, use a soft, damp cloth to gently wipe the coasters. Avoid using abrasive cleaners as they may damage the hand - painted metallic rims. Store them in a dry place when not in use to keep them in good condition. Remember, these coasters are covered by a 30 - day return policy, so you can shop with confidence.
