These tags are deeply engraved & will last a lifetime! We offer tags in copper, aluminum & brass in 1" & 1.25" sizes. Keep in mind that the design will be slightly different on each size in order to scale it up or down. I can engrave whatever information you need on the back of each tag. Our tags are thick & durable & should last a very long time! Copper & brass will tarnish over time, so don’t be alarmed when they start to darken. Many people actual prefer this look! If you would like to restore shine to your tag, there’s many natural ways to do so from home. Don’t see a design you like? Shoot me a message, & I can work on something custom for you.
