Black wind proof butane lighter
These metal lighters engrave crisp and clean. They are powder coated so they work with co2 lasers no problem. Basically it works by removing the powder coat and leaving the metal exposed. Lighters do not come with gas/fluid and are completely safe to laser engrave.
Recommended to engrave at a high dpi and power. You want to make sure you get the powder coat off completely. Use a sponge or cloth to wipe it down after and that will leave you with a clean metal shine.
