Each steel insulated tumbler/mug/jug is engraved through the powder coat to show the silver/steel. NOT screen printed.
*100% bpa free *good for hot and cold stuff *dishwasher safe but I personally always hand wash my tumblers just to be safe. *Engraved by another awesome small shop friend here in the US.
Like all things over time there may be wear/scratches/chips on the bottom of your cups. I have been using mine regularly and they're in great shape and I chose these because I love the quality and I hope that you do, too!
