Oil Based Queen Marking Pen is used for marking the Queen with oil-based paint. The color characteristic of oil markers is glossy and opaque, with the effect of enhanced radiance/reflection of light for easier detection of the Queen. The marker contains a ball in its body, which is designed in such a way that it maintains a homogeneous color structure inside the marker during operation. Before use, it is necessary to shake the marker strongly after which the top of the marker should be pressed against a solid surface several times so that the paint begins to soak the tip. The width of the tip on the marker is 1.2mm.
