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!
