Item did not arrive, but I contacted the seller and they sent a replacement without any hassle. As far as I can tell the tag is exactly as advertised. It appears to be stainless steel (heavier than aluminum, not attracted to a magnet) and the lettering seems to be laser-engraved rather than printed like I was worried it might be. The engraving is pretty shallow (which is typical for a laser engraver on metal) so I'm not sure how it'd stand up to abuse, but my dog is pretty sedate so it's not likely to get beaten up.
