This is a Raku Jewel silver 925 extra-thick azuki chain. The size is 45cm, and the thickness is an impressive 【7mm】. While the weight of a typical chain is around 15g, this one weighs 45g. If you're looking for a necklace chain and have come across this page, you've probably been looking at various prices. Azuki-type silver chains increase in price and rarity as the length and thickness increase. The general thickness (standard size) for azuki chains is about 3mm, but as you go up in size to 3.5mm, 4mm, 4.2mm... the maximum thickness handled by most shops is usually 4.8mm. This chain boasts a thickness of 7mm while being slightly longer than 40cm at 45cm, making it a unique piece that you're unlikely to see anyone else wearing. It features an easy-to-use lobster clasp, allowing for easy one-handed attachment. Unlike hook-type clasps, it won't come undone while you're wearing it, so you can wear it outside with peace of mind. As mentioned above, it's almost impossible (or very expensive) to buy again if you let it go, so I'm hesitant to sell it... but sadly, the size doesn't fit me, and I'd rather someone use it than keep it as part of my collection. The brand mark and lobster clasp are attached with split rings, making them easy to remove. In fact, I tried to lengthen the chain several times to wear it, so the split rings have small scratches. However, since they are small parts, I don't think they will be noticeable when worn. I think it would be fantastic to incorporate your favorite brand's parts and adorn your neckline. Before listing, I polished it with a silver cloth and then cleaned it. Therefore, I think you can use it comfortably. Highly recommended. If you are looking for a chain and 45cm is the perfect fit, how about it? Thank you.
