Premium Round, Large (2.125")
These are a durable metal and the colors are vibrant. One of the clasp came broken but received a new one quickly. Customer service was responsive and quick to resolve the issue. They are bigger than I thought but still work for my wedding. I am satisfied with the print quality and surprised at how vibrant the colors are.
