The Gundam Marker for shading is designed to finish up the model to make it look more "mecha" like. 

GM01 ~ GM03 Gundam marker for ink drawing is super thin for painting engraved lines, and they can give you a more mechanical looking finish. Paint run off can be erased with a rubber eraser. The marker ink fixes really well, so it is extremely easy to use.

3 colors are available, so you can use them for wide range of purposes.

• Black : For parts with dark colors like blue and gray
• Gray : Optimum for white parts
• Brown: For gold plated and red parts
