These are sleep sacks that my twins wore when they were 3 years old. There are two sets. The Anpanman pink and yellow ones have a fleecy lining and are a bit thicker. They fasten with four buttons. The cat and snowman ones have no lining and are made of a soft, comfortable material. They have a zipper. Both were very useful during winter sleep. There don't seem to be any noticeable stains, but there is some pilling from washing, so I've listed them as having some minor wear and tear. I hope they reach someone who is looking for them.
