I have been rather curious as to why the BA CW wash bag pen is a generic black plastic thing without a BA logo?

I'd have thought that it might be worthwhile for BA to hand out plastic ones with BA logos printed on them, a bit like hotel ones, for advertising value? Or is it too expensive and not very effective, given the number of wash bags involved for CW?

I also think it might be a good idea for BA to supply their cabin crew with pens for use at work, given they are mostly using random pens, often from a hotel, when processing duty free sales etc? They just look a bit random, although I'm not complaining (not something I'd think of complaining about).
