This is a double-point refill designed by Uni. The ink has good light and water resistance. The ink is evenly and not easy to leak, so the writing is stable and smooth. The refill uses water-based pigment ink to write clearly and does not stain the surface of the paper, and it will not smudge when exposed to water and will not fade easily.
