I purchased this on a cruise ship a while ago, at a shop on board. I believe the purchase price was around 7,000 yen. It's from the American accessory brand Brighton. I've used it two or three times, but I'm not wearing accessories as often these days, so I'm selling it to declutter. I've included information about Brighton, found using AI, in image 8. The total length is 110cm, and it's designed to be worn doubled. You can also wear it in various ways, such as making the first strand go under your collar for a single-strand long necklace look. It has eight decorative parts, and one of them is movable.
