Material: pt850 Length: Approximately 45cm Width: Approximately 0.8mm Weight: Approximately 3.62g This item was purchased around June of this year. It's a rare 4-sided herringbone chain, which is rarely featured, so I bought it immediately after seeing it on GSTV. However, I haven't been using it, so I've only worn it about three times and have kept it in storage. I'd like to sell it to someone who is looking for it! I've used it three times, but it's very clean and in beautiful condition! Please refrain from purchasing if you are concerned about used items kept at home or if you are seeking a perfect item. I look forward to your purchase if you understand. No pets, no smokers. Returns are not accepted. It will be packaged in a jewelry case (the GSTV one in the photo) and shipped via Takkyubin Compact.
