Although I expected a flexible tip on this 'brush' marker, the 1/2" tip is saturated with bright color that flows effortlessly with the slightest contact with paper. I think these were meant to be used with stamps, applying the color to particular areas of the stamp's surface, but they are EXTREMELY satisfying to use directly on paper. Just know that the tip is NOT flexible like a paintbrush. Despite this, they deliver rich, luscious color that makes doodling magic. I love them, and will order again.
