Customer wants to put tiny labels on metal baseball bats, rec district type thing. They want their logo and the word "approved". I'm picturing those hard plyable metal type labels businesses use for serial or asset tags? Anyone know where I can purchase those? OR!!! Would any of those spectra lights do the trick? They don't want anyone to be able to peel off so that's why I wasn't thinking spectra lights... anyone have any ideas what would be the best use?
