Xylene/toluene-free permanent marker with a bullet tip, suitable for most surfaces. Black ink produces legible marks designed for everyday office and industrial tasks.
Reliable, consistent marks - with a 5.0mm bullet tip
Bullet tip measures 5.0mm and provides a stable contact point that lays down an even black line for general marking. The tip shape resists snagging when used on typical office and warehouse materials.
Consistent stroke width makes labelling, packing and signage quicker and more legible, reducing time spent re-marking and improving clarity across workspaces.
Safer indoor use - thanks to xylene/toluene-free ink
