I choose this chain because I wanted something a little different, a bit more delicate than the traditional box or snake chain.  Although it is hard to tell from the photograph, this "Rolo" chain is made up of small, interlocking circles.  I purchased the chain in a longer length, and I find that it works well with a smaller pendant.  An added bonus is that it has a lobster clasp for extra security and ease of use rather than the more common spring-type clasp.  Overall, I am pleased with this purchase and would recommend this chain to others.
