I've purchased these twice now, the lilac.  If you are interested, purchase as soon as you see them listed.  I was on a wait list twice.  The wait was never more than a week.  While they are delicate they are of a sturdy material.  I think they will hold up well.  The grommets are a brushed bronze color which was just what I was hoping for.  I was prepared to have to paint them but was surprised.
