The Real Touch Marker GM401 by GSI Creos is a 2 in 1 Gundam Marker!
In fact, it's equipped with tips at both ends: a large one and a fine one. This way you have the opportunity to work comfortably both on large areas and on small details (and panel lines).
Color: gray 2 (asphalt gray).
It can be nuanced using the special Real Touch Marker GM400 (sold separately).
