Eraser for high strength bolt line markers.
Apply with the line you want to erase.
Eraser pens are pin-point erasable and pen-style for safe carrying and erasing work.
Please do not open the screw on the shaft, as the ink will leak.
Press down the tip too much will cause the ink to leak.
Always cap after use.
Porous writing lines such as wood and concrete cannot be erased completely
