This is a set of two, white & gray and pink & blue (3m each). It was also good that it can be washed in the washing machine. Here is the URL of the shop where I purchased it: https://item.rakuten.co.jp/shop-shimodai/samahua4/ I don't see any noticeable scratches or stains, but there may be some oversight, so I'm selling it at a low price. I used it to prevent my baby from bumping their head when sleeping on an adult single bed. I've included a picture in the second photo for reference of the width and thickness.
