Mr. Weathering Liner is a completely new weathering paint material, which can be used easily as though it were a pencil. You can use it not only on a plastic surface but also on glass surfaces. If you rub with a cotton bud, etc., an authentic smudged texture can be realized easily. It can be used not only for weathering painting, but also for the effects necessary in scene model painting including handwritten letters. 3 kinds of liner sets (3 colours in each set) are released.
