CD and film markers

With a film marker, first decide whether the writing has to stay put: Schneider 220 S, 222 F and 224 M are permanent, while Schneider 225 M and Faber-Castell Multimark are non-permanent. Then pick the line width: S, meaning 0.3–0.4 mm, for fine writing, F 0.7 mm and M 1.0 mm for a more legible mark. Edding 140S has a 0.3 mm tip and Edding 152M a 1 mm tip. Schneider S 220 also comes as a 4-colour set.
