The product is very durable and light. The paint does not chip and will make an excellent gift. The colors are bright and clear not smeared or muddy it's great.

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!
