I'm selling these at a low price because I purchased a large quantity. This is a petal chain necklace. Brand new, unused. Total length: Approximately 50cm Chain width: Approximately 1.1mm Weight: Approximately 0.84g Plate width: 3.1mm Platinum 850 Pt850 hallmark present Purchased from a chain shop in Okachimachi. Made in Japan. The petal chain, which means "flower petal," has a design that sparkles and shines by reflecting light on the center surface of the chain. The opening of the round clasp, which is the most easily broken part, is also welded for peace of mind. I also have 40cm and 45cm lengths available. Other lengths can also be made to order.
