I've been hunting for river stones with my kids every weekend, and these markers with the brush tip have made blending colors on the rock surface way easier than I expected. The paint goes on smoothly and doesn't chip after it dries, even on the bumpy parts of the stone.

The flexible brush tip blends colors surprisingly well on river stones, and the fine tip nails the tiny details without dragging. My mugs came out looking almost like real paintings, though I’d suggest pressing lightly at first to get the hang of the ink flow.

I was a bit worried the fine tip would be too scratchy on rough stones, but it holds up great for outlining little flowers before I switch to the brush tip for shading. The dual tips are perfect for going from detailed lines to smooth fills on the same mug without swapping pens.
