The Phantom of the Opera by Gaston Leroux The Phantom of the Opera ink is an ink that exhibits a striking red border that appears on top of a dark cobalt blue base, resembling a single rose blooming in the cold, dim underground of an opera house. The deep blue base creates a sense of mystery and depth, while the bold red outline provides a striking contrast that catches the eye. The label that is covered by a mask can be attached and detached. Shading & sheen ink, 30ml
