The 0.5–5 mm flexible brush tip glides smoothly over glass without skipping, and the dual-tone design means I get two shades per pen. I've only used about ten of them so far for a rock painting session, but the color payoff is rich and the tips haven't frayed at all.

The dual tip design is such a clever idea—flip it over and you've got a second color ready without digging through the box again. I've been using them on glass jars and the 0.5-5mm brush tip glides smoothly without skipping, which is exactly what I needed for fine lettering.

I paint rocks for my garden and the flexible brush tip glides exactly where I need it, even on curved surfaces. Having 144 shades in one box means I rarely need to swap pens mid-project, and the colors stay vibrant after they dry.
