SS tumbs -vs- PC tumbs

I’m sure most have done the powder coated tumblers on CO2’s and Fiber.

Has anyone engraved on Stainless Steel tumblers with logo’s and the such with Fiber?

I’ve got a couple from Dollar Tree sitting on a shelf I may play with later today, once I get caught up on things, but I was wondering has anyone done them for resale, and how did they come out?

More curious than anything.
