Premium Round, Large
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.

Beyond expectations. Choice of artwork is overwhelming, I found exactly what I needed from SJW_Graphics. Detail, colors, overall design looks great on this keyring. Could use as a pendant, purse charm, bookmark, too! Metal is sturdy without being heavy. Colors beautiful, with clear margins. Customized name makes this gift extra special. So many fonts, so many colors & sizes!
