I ordered three of these necklaces, 20", 24" & 30", on a Tuesday and received them on Friday. All 3 of them came in one gift box. Very fast with the delivery.
These chains are very sparkly, very thin & delicate looking.

I bought these three chains for my adult daughter, the three lengths looked great on her. My daughter has, thick, long hair about to the middle of her back.. which will be relevant for this post.

She opened the box, loved them, and put them on right away... the 30" chain was long enough for her not to have to open the clasp.. she just slipped it over her head.. the other two chains she needed to open the clasp and put around her neck.
All three of them, together, looked very pretty.
After 10 mins of wearing them she said something about the chains pulling her hair.
After 25 mins she had me help her get the chains off her neck because she said it was painful.. the chains were tangled in her hair and pulling strands out. It did take awhile for me to maneuver the chains, to pull the least amount of hairs out, to get them off.

After I removed the chains I thought.. well I just paid for these three chains for only 25 mins of wear because she'll never put them on again. But then I suggested that maybe if she wears her hair in a pony tail or up in a clip this might not happen. I know she won't get to wear them as much as I would have thought she would, now that her hair has to be up in order to wear them, but it's better then her putting the chains away and never wearing them again.
