This is a waterproof sheet I bought on Rakuten. It's for things like spills from a child seat or stroller. I bought it just in case, but I only used it twice in the child seat. There were no spills, and my child didn't like it, so I mostly kept it stored in the car. Although I didn't use it much, I stored it for a while, so there are some dust stains on the white backing. I washed it, but they didn't come out. The surface still feels fluffy, just like when I bought it. Please consider this if you don't mind minor spots or dust marks! I'm also selling a matching pillow! I'll offer a discount if you buy them as a set. I plan to send it via Yu-Yu Mail, which is a folded, postal-delivered service. Price is not negotiable.
