The writing feels smooth and lubricated, with fine and clear lines; it dries quickly. The grip is comfortable and does not cause fatigue after long-term writing. It adheres well to very smooth surfaces, making it suitable for writing on ceramic, whiteboards, glass, and other smooth surfaces. On whiteboards and plastic products, the lines are easy to erase after drying, leaving no trace. Remember to close the lid after use, and do not store it in a place with direct sunlight to avoid the ink drying up.
