Design on a Zippo lighter

[LloydCain-1957]

It's been a while since I designed something for a Zippo lighter. Tried again today but cannot see a way for the design to go on both sides. Cannot find an option (or layer) for the back side. What happened to this option? Is there a way to get it back? Would appreciate any helpful advice.

Thanks.

So far as I know they've always been print on one side only.... my oldest designs go back to 2017 and they were single sided then.

Thanks. I did look at some of my older designs and discovered the same thing. Getting older. My memory isn't what it used to be.
