yup,just basically fine tipped "gundam markers" in different colors.you should be able to find them where ever you can find gundam model kits 

 

Awesome, thank you! I'll go try to find one this week and work on Unicron. What a nice easy way to do my first custom  

 

Oh, is there a reason you didn't just use the black on all areas?

 

i used black on the darker grey areas,grey on the lighter grey areas and brown on the orange areas,just to help it blend in more as opposed to black on all.

 

Thanks for the tips. There's a Games Workshop near my office I'm gonna try to hit today and see what they have. Otherwise it looks like I need to order these online.

 

only pen i've been able to find is a black micron 03. is that good enough?

 

Major improvement. To me, Unicron never looked grand enough, now I know why. There was nothing to show his scale. Lining him did it.
