Pristine baby hat made with baby-friendly materials like organic cotton. Only washed once. There is no size label, and I'm not sure what size it is, but the width when laid flat is about 23cm. Based on baby hat sizing, I think it's approximately size 46-48. It seems like a good size for babies who are wearing hats for the first time. I bought it at a store for around 8,000 yen. I bought it because the pattern was cute, but my baby outgrew it before they could wear it. Please refrain from purchasing if you are concerned about minor details, as it has been stored at home.
