Gundam marker for ink drawing is super thin for painting engraved lines, and they can give you a more mechanical looking finish. It gives the model a three-dimensional feeling and makes it appear more realistic. Paint run off can be erased with a rubber eraser. The oil-based marker ink fixes really well, so it is extremely easy to use.
The effect is stronger when you choose the ink color according to the color of the model parts. In general, you can use black for dark parts, grey for lighter parts and brown for red or golden parts.
