Used it to label my glass spice jars and ceramic plant pots, and the white really pops on both surfaces. The 3mm tip is perfect for clean lettering, and the ink dried fast without any smudging when I handled the jars right after.

Wrote my son's name on his black bike helmet and it's still there after two weeks of rain and rough play. The paint goes on thick and covers dark surfaces in one pass, no shaking or bleeding through the 3mm tip. Only wish it came in a two-pack since I'm already planning more projects.

The 3mm tip hits that sweet spot for detailing—fine enough for lettering on my plant pots, bold enough to cover dark rock surfaces in one pass. Ink’s been holding up through a week of rain on the garden stones, which is exactly what I needed.
