These are accent brooches featuring a "Kachimushi" (winning insect) bee design. They're lovely. There are 8 available, so please consider purchasing them as a set. They were originally attached to a dress like buttons. I haven't used them since I bought them. They came with a dress, but I removed them and stored them unused. Please feel free to use them if you'd like. Please view all the images to check the size, etc. You can attach them in a row like buttons on a dress, or use them as an accent on the collar of a jacket, a bag, or a hat. Fastening type: "The back is a safety pin (brooch pin) type." The "Kachimushi" is said to have good luck because it can only fly forward and cannot retreat. See image 6 for packaging. They will be wrapped in packing material and placed in a plastic bag to prevent water damage, and shipped via Yu-Packet Post Mini. Please see image 6.
