This is an extremely thick curb chain made of sterling silver (925). The size is a long 55cm, and the thickness is an impressive 【4.8mm】. The purchase price was approximately 30,000 yen. If you're looking for a necklace chain and have arrived at this page, you've probably been looking at various prices. Curb-type silver chains become more expensive and rarer as the length and thickness increase. The general thickness (standard size) for curb chains is around 3mm, but then you have 3.5mm, 4mm, 4.2mm... As you look for thicker chains, the maximum thickness usually available in shops is 4.8mm. This chain boasts a thickness of 4.8mm while being a considerable 55cm long. It has an easy-to-use lobster clasp, allowing for easy one-handed attachment. Unlike hook types, it won't come off while you're wearing it, so you can wear it outside with peace of mind. The lobster clasp is connected with a split ring, so you can easily remove it. I think it would be great to add your favorite brand's parts to decorate your neckline. I've changed my hobby and no longer use it, so I'm selling it because I'd rather someone use it than keep it as a collection. Before listing, I polished it with a silver cloth and then cleaned it. Therefore, I believe you can use it comfortably. Highly recommended. If you're looking for a chain and want a 55cm chain that has some room around the neck while still making a statement, how about it? Thank you.
