This is not a pocket keychain: is too large. The front has the elegant PI image; the rear is metal. The front has the elegant PI image; the rear is metal.

Premium Round Keychain, Large (5.397 cm)
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.
