My son and his wife just bought a new house and had a new baby. They plan to build a gallery of pictures up the steps and loved this set. In fact, I might get another one!  They are well made and I received them in perfect condition and very quickly. 

Pros: They show you different examples of how you can arrange them. The black goes with white and silver should they decide to mix colors. And, there is a variety of sizes which makes it interesting.
Cons: I can't think of any negative thing to say. As I said, I might order another set. Thank you.
