This is a set of a headdress and earrings. I used them once for a wedding, and they are in beautiful condition. I think the colors in the 3rd and 4th photos are the closest to the actual items. I forgot the name, but it's from a handmade artist who was popular a few years ago, and I think the product was called "Komorebi" (sunlight filtering through trees). I remember it cost around 10,000 yen at the time. Please feel free to ask any questions in the comments.
