These tags are bright and shiny with good clear engraved print. I put this on 2 months ago and it's been through the washer a couple of times with no damage. Looks just like new. I don't think it's made to be moved from one collar to another as it is thin metal. But put it on and leave it and it should last a long time. It's great that there are no dangling, clanking tags on my dog now. I have one on her collar and one on her harness. I recommend.
