I bought two.  They are lightweight which is what I need.  In the question/answer area someone asked the length of the chains.  The seller wrote back that it's 24 inches.  Both of mine are 18".  The 24" is one reason I ordered these.

Aside from that these are great pendants and I will put them on a longer chain today.

Oh, BTW, the shipping was very fast.  Another plus!
