Mr. Hobby - Fine Line Gundam Marker - Black

A pouring type of Sumi insert pen appears in the Gundam marker! If you knock the pen tip on paper etc. and moisten it with ink, just apply the pen tip to the mold! It flows smoothly into the mold and can be inserted! You can erase the part that overflows with the eraser, or "GM300 Gundam marker eraser pen".
