.....What pens do you use for writting on such things as the RS "Tested", "calibrated" etc labels, we have used for some years now the "Edding 8404 Aerospace Marker" and for the past few months they have been crap! the aerospace industry must be in quite a bad way, having to guess where the lines were!.
They worked ok new and stop within a couple of days, please save me some money and tell me which ones work?

Thanks guys
Matt.
