Another new product from Hobby Mio, born out of your suggestions! Thank you so much for suggesting this item!
Hobby Mio's panel lining pens are exactly like Gundam Markers fine markers - easy to use and fits panel lines for Gunpla and other scale model kits. To clean up the ink, you can use lighter fluid on some q-tips.
Pro tip by Mars:
Use BLACK panel line for dark colours panels like green and blue. Not recommended for white panels, since the black panel lines can make the model look jarring.
Use GRAY panel line for white panels. It gives a subtle pop on the panel line.
Use the RED-BROWN panel line for yellow or red panels!
