This is a K10 Miami Cuban chain from GRILLZ JEWELZ. It is a solid type. Regarding the links, they are the type where two links make up one. Please refer to image 6. *There is one place where the links are single, but there is no problem with the appearance or wearability. It has a good weight and I liked that it wasn't too flashy, but I'm selling it to put the funds towards another necklace. There may be some minor scratches, but I cleaned it regularly, so I think it's in good condition. The clasp can be securely fastened ^_^ The current retail price is ¥252,014. I think you can buy it for a little less, so if anyone is interested, please consider it. - Brand: GRILLZ JEWELZ - Color: Yellow Gold - Size: Length 51cm including the bale Width 3mm Thickness 1mm - Weight: Please refer to the images - Style: Miami Cuban - Material: K10 Yellow Gold (Solid)
