I found a 4 pack of flip top lighters. They look like zippos but they’re not. No biggie on my end. I was able to get 1 of them the engrave and one to sorta engrave, but the other 2 won’t take. I’ve tried mustard and molly lube but nothing takes. It’s like the laser just doesn’t even see it.
Anyone have any suggestions on what might work? The black is the sorta took. I don’t have the one that took handy atm. The other 2 have both been run under the laser multiple times.
