- Uni-ball eye “ultra micro” is the first roller ball in the world to have a size of 0.38mm with bullet type tip. In order for the ball inside the tip to work and write properly, the ink of uni-ball eye “ultra micro” had to be re-designed and adjusted for this extra fine writing. The ink is of course uni-super ink which makes it resistant to light, water or any other chemical.
