koo-die's waterproof mat, Rain Cloud (light blue). You can put it in a child seat or stroller and use it for leaks or food spills. I used it 2 or 3 times, but it never leaked. It's in a clean condition. I bought it for 3,520 yen. Please understand that this is a used item before purchasing. We also welcome combined purchases with other products.
