These heat-resistant PVC coaster pads are great for your dining table. To use them, simply place them under bowls or hot dishes to protect your table. When it comes to maintenance, you can easily wipe them clean with a damp cloth. Remember, the size is manually measured, so there might be a small difference. Also, the color you see on your screen may vary slightly from the actual product, but don't worry, it won't impact how well the pads work.
