This is a set of Familiar rompers, size 50. It was the perfect size for my daughter, who was born weighing about 2800g. Both were purchased in excellent condition on Mercari and worn for about a month. I had other clothes prepared, so they weren't worn very often, and there are no noticeable scratches or stains, but there is some wear and tear from washing. Please purchase after confirming the condition in the photos.
