Seem to be of high quality steel and are reflective. They laser well and was able to get some good color with the F1 Ultra.

Awesome outcome when colors are added while engraving at different speeds and power

These are great product. I easily engraved and my customers loved them!!

These are high quality and a fantastic price

This keychain is just the right size. I engrave these primarily with the xTool F1 Ultra using the fiber laser. Dialing in the settings to achieve different color effects can be a little tricky, but once you've got it down, the results are consistent. On a side note - I wouldn't bother with any of the jig templates. Placement with the camera is a lot easier than I thought it would be.
