I believe this is a rare, not-for-sale pajama set. It's probably about 20 years old. It's been stored at my parents' house. It has the SUMITOMO LIFE logo on it. There's no size indicated, but it seems to be a slightly larger fit. I think it's probably unused, but there are no tags. Please understand that it has been stored at home for a long time, so there may be some oversights. Only those who can accept this should purchase it. The colors are vibrant, and I think the condition is good. Please feel free to comment if you have any questions. ☺️
