Mr. Hobby Gundammarker for Plastic Model Kits - Grey (liner type)
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.
There are 3 colours available, so you can use them for wide range of purposes.
Great for Panel Lines
