This is a Richell bath mat that doesn't get cold. It was helpful during baby baths. I'm selling it because my child has grown and no longer uses it. I think it's still usable! Usage period: February 2025 - April 2025 It was washed and dried after each use. I will wrap it in bubble wrap and send it.
