Gundam Markers (for your Gundam job) that I recommend to have are
GM01-Black Fine Tip
GM03-Brown Fine Tip
GM100-Chrome Silver (or GM05 if you can't find it.)
GM200-Chrome Gold (or GM04 if you can't find it.)
GM06-Blue
GM07-Red
GM08-Yellow
I don't recommend GM300-Eraser to be an eraser because I use my finger to rub on the color (when it's nearly dry), it look fine that use Eraser.
