Thank you for viewing. Reliable Japanese product. Water-repellent finish prevents water from splashing and soaking in during bidet and posterior cleansing. It's about 7mm thick, providing a soft and comfortable seating experience. I purchased this last winter, but I'm selling it because I haven't used it. It's a set of 3 colors. Although it's unused, it has been stored in a chest of drawers, so please refrain from purchasing if you are concerned. m(_ _)m
