Engravable Cubic Zirconia Star Pendant Necklace

Clasp is too difficult to close once again - there's no bigger ring/hole at the end of the chain, to allow you to insert the hook into. All my other necklaces do have this. It's very annoying and damages your nails. I already gave this feedback for the last necklace I bought and this one is the same - why are they not finished properly in that regard, especially given the price?
