With these oil-based pour type markers you can apply ink to engraved parts by only putting the tip of the pen to the mold, it smoothly flows along the panel lines. You can use a rubber eraser or the Gundam Eraser for excess paint.
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.
This pen can not be used on painted products, because the ink melts to the groundwork. For painted parts we recommend Gundam Marker Brush Type pens.
