This item is (10) 6mm Gold-Filled Spring Ring Clasps.
Great for use with a Split Ring or Jump Ring.
These Clasps are Gold-Filled NOT gold-plated.
Gold-filled findings are a base metal with 14K Gold heat and pressure bonded to it. Unlike Gold plating, it will not wear or flake off. The Gold you see is indeed 14K gold and the findings tend to hold up better than pure 14K ones due to the strength of the base metal center.
