The Pentel Marker X100-L (White) is a permanent marker featuring white, pigment-based ink suitable for marking non-absorbent surfaces such as glass, steel, and rubber. Its durable, chisel-shaped fiber tip allows for variable line widths of approximately 5.5–6.5 mm. The valve-controlled ink flow ensures even application, while the aluminum barrel provides a robust design. It is an excellent choice for industrial applications requiring clear white markings.
