The extra-fine 0.7mm tip is a lifesaver for tiny details on dark rocks—it flows like butter and hasn't clogged once after a dozen uses. My glass jars finally have crisp, permanent labels that survived a dishwasher cycle.

I was skeptical about getting a clean white line on dark glass, but the 0.7mm tip flowed smoothly from the first stroke and didn't clog once. Wrote on a black stone and a dark wooden frame, and both dried to a nice opaque finish without any bleeding.

The 0.7mm extra-fine tip gives me crisp, clean lines on dark glass bottles without any smudging. Ink goes on opaque white and holds up even after I accidentally ran one under water.
