Thank you for viewing. This is the ah oui Post Slide Chain Filante Necklace. I purchased it on Rakuten Ichiba. It is usually sold at a length of 45cm, but it has been extended to 60cm. Material: 18K Yellow Gold Length: Approximately 60cm Weight: Approximately 1.76g Size: 0.24 cut azuki chain (width approximately 0.88mm) Free ball slide type / End part twist pin approximately 1.5cm Total length = fittings and chain *Does not include the twist pin of approximately 1.5cm. (From the official page) Current reference price: Approximately 40,000 yen (Regular price 30,000 yen + length extension 10,000 yen) This is a pin necklace that uses a pin for the slide fitting. Unlike general necklaces, one of the fittings is pin-shaped, so it can be used with pendant tops with small holes. It will be shipped without a box, wrapped in bubble wrap, via Yamato Takkyubin Compact. Material: K18 (18K Gold) Color: Gold
