Pros : There is a good variety of colors but as a beginner I was used to buying glass that was much larger than these pieces; so be sure to pay attention to the measurements.
Cons : Also they do say that the glass is sometimes irregularly cut but on piece was missing an almost 3" square from the corner ... And it was one of the really pretty colors.
Other Thoughts : Just beware and remember, you do get what you pay for.
