GSIクレオス ガンダムマーカー グレー（細）GM01/GM02

Gray’s my go-to for panel lines now, and the fine tip stays sharp even after a couple of hours of detailing. It flows evenly without pooling, so cleanup is barely needed.

The fine tip glides into recessed lines without any smudging, which made panel lining my latest kit feel almost effortless. I picked the Gray version and it reads as a subtle shadow rather than a harsh black outline, exactly what I wanted.

The gray tone is just right for panel lining—dark enough to read clearly but not as harsh as pure black. Tip stays sharp through a whole kit, no bleeding into the plastic.
